After some difficulties to sync my DBs through Bonjour I started to use the app (I have as already said some lagging and hope the next version will improve this).
I bought the pro app-in as I wanted to annotate my PDFs and it works pretty well
What I wanted also to do is to use DT2 in split mode view as I wanted to write reading notes in parallel with my notes taking app Notability.
But, each time I tried this DT2 freeze (blank screen with DT logo) and crashed.
Just checked - working fine for me. iPP 12.9" - and the split view has worked from when I initially installed DTTG on iOS 9.x, until today, with iOS 10.x.
Try uninstalling, doing a hard reboot, and reinstalling DTTG2. I use split view frequently – iOS 9 and now iOS 10 – without crashes. Actually, DTTG never crashes on iOS 10. Thankfully.
Before to install again DTTgo I tried something.
I open first my app Notability then I open the split view window and then select DTTgo and then no crash…
I can go through DTTgo and open PDF file to annotate them
Strange…
