I have updated my z fold 7 to cloud and to Google no issues. My watch and my phone are fully charged and still it wont do a backup.

Me too having exactly same problems... Galaxy Fold 7 & Galaxy Watch 8 Classic, every now & then warning not backup for more than 100 days.. since day 1 using Watch 8 Classic to be exact. Tried every possible suggestion for both devices - reset, re-pairing, update, min battery >30%, screen off, wifi connection, etc.2... still none works!!! Previous Fold 7 + Watch 6 Classic no such problems... Tried report to Service Center but they also no idea how to resolve these problem!!!

I concluded either my Watch 6 Classic or Samsung Cloud got problems since its working with my Watch 6 Classic...

Saw in Reddit need Samsung Smart Switch apps active on both devices... trying and see
