People in touch with Samsung are expecting Samsung to release an update in March to fix this issue.
In the meantime possible workarounds are as follows :
- Disable AOD mode
- Enable Background Activity switch (not working on all devices) https://www.reddit.com/r/GalaxyWatch/comments/swaw8y/thirdparty_watchfaces_aod_mode_solution/?context=3
