ios 15.0.2 excel v2.54 not opening files stored on iphone when on LTE
I have a bunch of xlsx files stored on my iPhone. When I'm at home and on WiFi I have no problems opening any of the excel files stored on my phone however if I turn off my WiFi and then try to open the excel files I get an error saying "Opening: [FILENAME]... Downloading from iPhone..." and it just hangs up. My wife is on the same excel version but still on iOS 14.8 she has no issues opening the same file saved on her iPhone (on WiFi or LTE) so it seems like the bug is on iOS 15.0.2.
Any known fixes I could try?
iPhone 11 Pro Max, iOS 15
