Garmin Connect App syncing issues

I use Garmin Connect App on iPhone and I recently encountered issues syncing some (only some) of the data from my Fenix 8.

What I can see on my watch does not reflect information on the App. E.g. Acute/ Chronic Load doesn't move since many days, while on my watch is recording all the daily changes.

Interestingly, Connect App records all of the activities with accuracy and every data from the watch, but the total Load value does not change/move.

It automatically affects some other data such as Training Status, including (interesting) Heat Acclamation...?

I've been having some software issues time to time, but never like this.

Btw, I already tried reseting both devices, deleting and reinstalling the Connect App, connecting to Garmin Express and so on.

I'm running out of ideas. Please HELP!
