Phone battery freezing on Wear OS watch

Hi to all

From this morning i’m experiencing a strange issue on my TicWatch Pro. The issue happens with all faces. The phone battery, simply represented in some of my faces with a phone icon and the tag #PBN#,
marks correct % when i sync the face. After that the phone battery % freezes. Phone battery goes down, but not in the watch that continue to show initial %.
Until yesterday it worked correctly.
Thanks for any help
Cheers
