Major bug persists: saves reduces quality

Google drive still has a major bug persisting, which is save to camera roll reduces the quality of the image.

A workaround that does NOT always work is as follows:
tap on three dots
send copy
save image

Issue persists that even the workaround will still randomly result in a reduced image. Only when you see “preparing to export” will the original size and quality image be saved to your phone. Unfortunately there is no rhyme or reason as to when “preparing to export” will pop up or not.
