I just got a replacement phone LG 4 and I cannot save photo edits?
I know this question is from May but in case someone else is having the same issue I will tell you how I fixed it with my phone. The same thing happened to my phone when it updated so I went into my Gallery App and made sure the storage permission was on and also make sure in your Google+ App the storage permission is on as well! This is what solved my problem with my phone not saving the photo edits.
