Yes this is a problem we updated last week and if you check on xda there are issues with SD card unmourning
Also if you check on this site Some Samsung devices have had the same problem It Google trying to restrict SD card access on Android but why ???
Hi
I had the same issue I think it because you have synchronised accounts and it has imported them they are not on your device but like on the cloud I think you have to unsyncronise and delte from Google drive or goggle plus
Good look !!
