Dear respected David Hassine,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
It seems you cannot properly use OneDrive app on your iPadOS 18.3device. For the situation you’ve encountered, I do understand the inconvenience caused and feel very sorry about it.
As per your description, this knows issue recently, I can confirm its a compatibility issue between Microsoft OneDrive app version and Apple IOS version.
Recently we've received many other users also have similar issue that they cannot properly use OneDrive app on their iPad version 18.3. I’m afraid this is a temporarily issue needs to be reported to related product team and investigated from back end to find the cause. The Microsoft Support Team has higher permission and advanced resources for Microsoft products than us moderators. This is a more efficient way in handling this case for you.
