This app used to be my favourite PDF management app. Easily a five star. Unfortunately the new version seems to be less consistent than ideal. The annotation tools stutter at times on my iPad Pro. The processing of pre-existing annotations also seems to be broken, with the problem of not displaying certain annotations or selection cursor drifting, especially for large PDF files where it used to be amazing. Not to mention the fact that this app becomes extremely power hungry than before. My iPad has never had any overheating issue until using this current version of Documents.
On the bright side, the sync process indicator is a welcomed addition, and now we directly move files to starred folders, which is very convenient.
*Update: the new update fixed some of the problems. But the app becomes less responsive. What a shame.
