Spotify CIQ App not working correctly

2 month later an no fix. I have the same problem with FR 245 Musik and OnePlus 6. 

• What is happening? (e.g. failing during setup, sync failure, playback failure, etc.)
  • I get "Sync failed" when trying to get playlists down on the device. I had music on the device, but suddenly I could not play the sync'ed music, and I cannot update/sync. It goes to sync, saying "Syncing Spotify 0% Complete", never moves, and then "Sync failed"
• What kind of phone are you using?
  • Samsung Galaxy S10e
• What kind of headphones are you using?
  • Well, I don't use headphones for sync'ing, but the headphones I used when it worked are Aeropex by Aftershokz.
• What Garmin Device do you have?
  • Garmin Vivoactive 3 Music
• When was the last time Spotify worked correctly?
  • Don't know, few months ago I think
• Does the problem only happen with a specific Audio File?
  • No.
• Are you using Public WiFi? (Using a Wi-Fi Device on a Captive Portal)
  • No. I use my own WiFi, first I changed from an SSID that is dynamic 2.4GHz/5GHz to a 2.4 dedicated channel. Then I tried using a hotspot from my phone. Non success.
• What software version is on your Device?
  • SW 5.60
  • GPS 2.50
  • Wi-Fi 2.50
  • TSC 2.00
  • ANT/BLE/BT 4.30
  • Sensor Version 3.20
  • WHR Version 20.03.31
  • Connect IQ 3.1.7
• Do you have a vivoactive 4 (Hero Series or Saga Series) device? 
  • No

I would note that I have tried with and without charger connected to the device.

Garmin-Matthew, any news on this issue?

• When I try to sync podcasts using Spotify it will start to sync and fail 100% of the time.  It will connect to Wi-Fi and start the process and get anywhere from 1-95% and then say sync failed. It never gets stuck at 0% but never ever has actually finished a sync
• Samsung Galaxy S20+
• I'd say irrelevant as never even synced once so haven't listened to anything yet but have Plantronics Bluetooth ones currently synced but not actually connected
• Vivoactive 4
• Never
• I have tried downloading multiple podcasts
• Home Wi-Fi, with password
• Versions
  • Watch SW version 4.50
  • GPS Version 2.90
  • ANT/BLE/BT Version4.30
  • Wi-Fi Version 2.60
  • Connect IQ 3.1.7
  • Spotify version 1.3.25
• Yes

I'm seeing almost the exact same thing as @swansoer with podcasts on my Google Pixel 2 / Vivoactive 3 music. Latest garmin software (5.60) and latest spotify (1.3.25). It goes very slow, gets to X% and then says "Sync failed". If I try again, it starts at the percent it failed at, but takes a really long time before the percentage starts increasing again, and the higher it was the last time, the longer it takes (as if it's really just restarting the download, perhaps).

It started happening in the last 2-3 days. It doesn't seem to affect music- I just synced a 51 track playlist with no issues. I tried uninstalling and reinstalling Spotify, and then even resetting the watch entirely, but the same issue came up again.

One difference I have noticed is that sometimes, the podcasts do finish downloading (maybe 10% of the time). And, a few times I have been able to finish successfully downloading on the failed previously. My likelihood of finishing a download has increased with being plugged in and close to the router, but still happens very often even when I do those things. It used to never be an issue at all with where I usually keep my watch, until the last few days.

I've recently changed my router and that combined with the latest update seems to have fixed it for me so far. 

For what my opinion is worth, I think this problem is related to Garmin devices not handling corrupt WiFi packets very well.  I have two places I sync in and the one with the most congested WiFi gets this problem more often.

Last time I looked, the CIQ command set doesn't even have a full set of error traps for wireless, meaning that if there is a communications error, it will just crash the app and there's nothing the app programmer can do about it. There appears to be a similar problem with Bluetooth.  In my experience, electromagnetic interference, like a passing train, can crash the BT headphones driver.  It's marginally better than before because you used to need to reboot the watch to recover.  Now you usually just need to wait a few minutes for the driver to time out but that's still a pain and still evidence of bad programming in the CIQ platform.

The forum is best for mutual aid and the more specific you are about the problem you're having the more likely it is that another user will be able to help you or suggest some workarounds. 

• What is happening? (e.g. failing during setup, sync failure, playback failure, etc.) Garmin watch says Failed to Sync when trying to download aSpotify playlist. its really frustrating as I’ve reset the watch and reinstalled everything from scratch and still no good. I’ll sit the watch next to the WiFi router and make sure it’s 100% charged and it’ll still fail.
