Installed PB3 on my 7+ a few days ago. Running fine with one exception: The size of my Photos library has ballooned by 3-4 times the size (~3GB to 11GB) resulting in my 32GB phone completely running out of space to the point where I can't take any more photos, email won't load etc. I thought photo storage was supposed to DECREASE with iOS11, but perhaps that is only with new photos taken using the new format (HEIF)? Anyone else have this issue? I may have to downgrade back to iOS10, but I assume I'll hit the same issue eventually when the public release comes?
