Connecting to the phone Venu 3

Presented Venu 3. Yes, this is not my first watch, I had to remove the previous watch first. Then it connected without problems. The next day, the watch offered to update and the firmware was updated to 7.07 and the watch stopped connecting to Garmin Connect. When resetting to factory settings, the firmware remains 7.07. Maybe fall back to 6.22 or solve the connection problem somehow.
