one drive app is good but lack a lot of feature which iCloud or dropbox have. This is the reason Microsoft losses market share because it doesn't upgrade function & more features of its native software.

The issues I'm facing:
Upload of files stops when phone is on phone goes on timeout or screen lock

Upload is very slow even if my connection is fast tried in 5 countries upload is ****

Doesn't auto compress heavy pic or video files like other apps while upload

For last 5 year same features just design change

Paid customer like me will think of moving to amazon or any other for better features & faster upload.
