We are experiencing an issue with the Sharepoint App on a users iPad Pro. The user keeps getting a notification "click to provide additional credentials" along the top bar of all pages. The notification message also keeps doubling making the header larger and larger when he browses back and forth between site pages. We clicked on the message, it brought us to a blank screen. I contacted Microsoft Support but unfortunately they could not be of assistance and requested I share my question with the Sharepoint online community to see if anyone has experienced this previously. I have uploaded a screen shot of what we are seeing. Anyone encounter this before?
