Latest version corrupts written annotations w/Dropbox – PDF Viewer - Annotation Expert Review

This app had been great, but the most recent version has been syncing corrupted versions of files with Dropbox. It does not seem to reliably write file updates back to Dropbox, and often when it does, some pages of the resulting file will have annotations (written with Apple Pencil v1) stored at very low resolution or distorted. At this point, those pages are irredeemably corrupted.
