Apple Watch updating randomly
I have a series 3 Apple Watch. Sometimes it will randomly show a screen with a white circle around the apple icon. When I go to the watch app on my phone, it says my watch is synching. This happens at random times during the day, several times a week and can take over an hour. The white circle keeps starting over again. During this time, I can't do anything with my watch and I can't find a way to stop the sync and try to do it at a later time. The latest system update is installed on my watch. Is this normal? Is there a way to only have my watch sync at night so my usage isn't interrupted during the day?
Apple Watch Series 3, watchOS 6
