Side note if this can help. This is getting worse as soon as I disconnect from iCloud and reconnect. I wanted to try this to see if it help. But after doing it twice within 2 days, once I reconnect the other storage is going dramatically up. I was at 25gb of other storage. Juste disconnect ans reconnected I am at 40gb of other storage. Time ans leaving the iPhone plugged in does seem to help! Please help!
