Updated to the official version of android 10 today, and I'm getting a constant notification saying that my sd card is unsupported, even though it was before and in the beta. The notification says to format to a supported format. I did that and it is still saying it is unsupported (I backed up my data prior). I have no idea what the issue could be and i cNt write to it or see the files on it anymore.
I am on a S10+ in the US with Sprint running the official version of Android 10 released today.
