I like the office lens iOS app, but I don't use Microsoft's cloud storage. I use icloud.
Office lense does not have icloud integration (or any other cloud storage), so I don't use the Office Lens app.
Users should have the easy option to chose icloud storage (or other well known storage solutions) for all save actions from the office lens app.
I left a review on the Apple app store, pointing this out, and was asked to leave feedback here.
Looking forward to your reaction.
However, I see something similar was asked a year ago here, and no reply.
