Whenever we try to upload to Box from the native iOS Files app or PDF Expert, we have to manually navigate to the folder we want to upload to.
If we try to search for the folder and then click on it, the upload window just closes. This has been tested on multiple PDF/File apps on iOS 15.7 and 16.2. We've tested with multiple accounts as well as brand new accounts.
The function worked fine before the most recent Box for iOS update.
