Update riddled with bugs

PDFPen (and the desktop Pro) version have been my "go to" for several years, yet the current iteration on iPad is nearly unusable:

1. Cannot trigger sync without closing window then reopening it.

2. Sync no longer runs in background.

3. Sync not updating changes (none of my updates appear in Dropbox, in spite of repeated forced syncs over the past 30 minutes).

4. Highlighting does not recognize finger drag across text—gets stuck. Only way out is to zoom way in, grab handle, drag until it gets stuck again, zoom in even more, grab handle again, etc. Takes several tries just to highlight a short sentence (single line).

5. After dragging items into folders (which I love), a grayed out copy remains on the screen outside the folder. Probably related to failures in sync process.

6. Moving annotation text box works about 1/4 of the time, if that.

7. Renamed documents dont reflect name changes in Dropbox (again...that sync).

And all this in one simple PDF document.

Breaks my heart to post a negative review for this app, but the update behaves more like an untested beta than a fully vetted version. ?
