I have looked at a lot of the forum posts, going back to 2014. I have a Nokia 8 (Android 8.1) and MTP is very unreliable with DO.
Problems I face are freezes, I cannot navigate via the tree - only the navigation within the lister using the up down buttons work and copy actions seldom work.
I have set MTP to false in the settings and everything works correctly in Explorer (Win 10 1809 17763.134).
Is this something you can fix?
Beyond Compare have recently fixed this so it must be possible
