Attaching files

Hello

I have a company iPad, recently each time I tried to attach a file it doesn’t give me the option to do open one drive. I click edit side bar and one drive doesn’t show as an option. This is when in safari and on the mail app. Also when it does work on Edge, when you choose attach, it used to take you to the last file you were in, now it goes to a standard home page so you have to click through all options to upload the file of your choice.

Any ideas please?
