| I received an email that I need to have Security Certificate update starting July 13, 2026, otherwise I won't be able to edit my work on word, ppt, and excel. To address that, the email said that I need to update my OS system to version 12 or higher and/or update any microsoft 365 app, which I all did but still couldn't edit using word or any Microsoft 365 app. |

And for your Msft 365, did you get it from Microsoft or from Apple App store?
