Hydration tracking does not sync

I just checked, my hydration data seems to be ok. I want to add though a issue with the hydration reminder. Even if I add my hydration the reminder still seems to go off. 

With your issue, do you have reminder turned on? 

I have a slightly different issue due to my VA4 doesn't want to connect via bluetooth.
I use the VA4 right now in some kind of USB mode where I plug the VA4 via USB on the computer and sync with the garmin express app on my Mac.

Everything seems fine in Garmin connect in my browser besides the hydration information.

Anyway, i can read the amount of water I drunk during the day on the VA4 and set the data by hand

I have the same problem, however, this feature was working for me before the malware attack, it doesn't work since then.

I have the same problem. It’s so frustrating!  It used to work fine. But I just realized recently that my hydration hasn’t been syncing for weeks. There are random times when it does but overall it’s not working. 

I have the exact same issue with my VA4. Some days the data shows but only for 5 days out of 35. I have an iPhone 11, the watch and the phone need to be constantly manually synced to have any sort of up to date information shared between them (weather etc ). The watch has been glitchy since I bought it and is not very ‘smart’, I wouldn’t recommend this watch to anybody going by my 5 weeks experience. 

Mines works some days but most days not - please can we be told how to get this working? thankyou

I am having the same issue. Unless I manually input the info into the app, whatever I put in my phone for hydration does NOT sync to the app, so it appears as if I have done nothing in that regard. Where is the answer for this Garmin?

Just found this, which is really counter-intuitive when everything else syncs without being on the "screen":

Syncing Hydration Data With Garmin Connect

Unlike other recorded fitness data, your fluid intake data will only upload to Garmin Connect when you are accessing the Hydration Tracking widget on the watch. If the hydration data in Garmin Connect doesn't match what you've tracked on the watch, follow these steps:

1. Navigate to the Hydration widget on your watch
2. Open the Garmin Connect app on a connected smartphone
3. Wait a few moments to allow time for the fluid intake data to upload
4. Swipe down on the My Day screen to refresh the Garmin Connect app or tap on "hydration" to see the updated data

I have found that if I have my watch on the screen with the hydration and I sync manually it registers. It’s not a good answer and garmin should do something about it

But I got it to work

Just an awful watch really isn’t it. Wish I’d have just bought an Apple Watch and saved the hassle of this thing. It’s as if it was made in the 90’s or something, really basic.
