fenix Chronos Software Update 18.1 breaking Bluetooth?

My Chronos updated automatically the other day to 18.1 and Bluetooth stopped working. I could not get my watch to pair with my phone. I did a hard reset back to 18.0 and bluetooth was restored. TODAY....my watch auto-updated again, and again Bluetooth has stopped working. Anyone else???

I have this issue with Bluetooth too. The problem start with beta 76 and still with 18.1.

Now when the watch turn on, it connect with the phone but when it start to sync, something hangs the process and watch stop the communication, and disconnect from phone. Only with a reset in watch make the bluetooth start again (but with the same problem when I try to sync). I can't sync now. I think is something with True Up but who know...

LuizMaia,

I might suggest trying to clear your Sync Queue in case you have something trying to Sync that might be causing the issue. If that fails I might suggest contacting our Support to troubleshoot that issue more thoroughly.

I didn't think that I have anything in queue, but just in case, I connect the watch with my Mac and made a complete sync.

But the problem still when I try to sync with the phone only using BLT.

I made a video if help the garmin dev team. I'm using a Galaxy note 8 and Android 9.

LuizMaia,

In doing some testing here I found that Restoring Defaults can help. If you don't mind restoring system defaults you might try to see if that fixes your issues. You can find the option through the Menu > Settings > System > Restore Defaults

Thanks for reply,

1) I made a restore to system default.
2) Make the pairment process with sucess, and the watch can sync again.

but when I turn OFF the watch and turn ON again the same problem return and the sync is not possible anymore.

:-(

I think that I have to wait to a new version.

I discover that the solution is not turn off the watch after pairing. The watch works connected and It can sync normaly. If I turn it off, only a new pairing solves.

Have have experienced the same as you my Chronos updated automatically to 18.1 and will not connect to my Samsung S10 5G only as it powers on will it connect then it disconnects. I have also done a hard reboot and finally got it working last night then this morning it had updated to 18.1 and no longer connects its 100% the 18.1 update
