Upside down/mirrored sheets and upgrade

[SimonH22]

All my existing and any new sheets are mirrored/upside down. I think I may not be using the latest version of Excel which may have fixed this but when I try and upgrade (from 15.31) on my Mac it continually say 'upgrade is in progress' and does not resolve. How can I successfully upgrade please, and will this fix the sheet issue? I have a Mac under Catalina

Thanks!

Regional settings will allow column A to be on the right to support the use of languages written right to left, such as Arabic or Hebrew.  Upside down would be a novelty.

I'm not on the Mac and can't say something concrete, but please check this thread https://answers.microsoft.com/en-us/msoffice/forum/all/excel-upside-down-and-backwards-after-upgrade... if helps

@Sergei Baklan Thanks very much indeed - the update finally completed somehow and that has fixed the sheet inversion and reflection (a well known issue it seems). Thanks for your help!
