Was just looking at what’s using space on my iCloud, and I see that the Sufferfest app is the biggest app on my iPad - at a hefty (for cloud backups) 400+MB. I suspect it’s actually backing up the offline-saved videos in the app, which make no sense - they can be re-downloaded anytime.
Is there anything else that the backup includes? I suspect no, and planning to just turn off backups for the app, but maybe someone knows better.
For the devs - not sure if you can mark things as “don’t backup”, but if it’s possible, it would help. 400+MB is about 10% of the default iCloud quota.
