Same here. I used to be able to click the photo icon on my comment bar on facebook and it would take me to the phone's stock gallery app but now it points to this completely unorganized and incomplete app that I can't even seem to locate on my phone (not the google one). This is very frustrating.
I have just setup my S21 Ultra and found the same issue. Is there any fix for this??
I just had to screenshot a photo I wanted to upload. Thinking I might have to just delete the gallery that transferred from my old phone..?
Have there been any updates on this issue? I just got my s21 ultra yesterday and this is extremely irritating. On iOS I can actually select an album within Facebook from which upload. On Samsung I can’t even see them in order? Not exactly user friendly.
