Hello,
This is a returning topic I guess. But without a solution to this we will end using BOX as organization. Is is impossible to work fluently without previewing files.
Is there a timeline when this issue will be solved? Previewing files is a basic feature that any other file platform gives.
So, is there a solution? Making files Offline available does not work!
