Hi!
Welcome to Microsoft Q&A forum.
Fixes are being released gradually, so expect resolution with the next Office build. Unfortunately, there is just one workaround by using the combined Microsoft Office.
- Install the “Microsoft Office” (all-in-one) app from the App Store.
- Sign in with your Microsoft 365 account.
- Open your Word or Excel files there, this version has slightly different rendering and is often unaffected.
OR
- Use Office.com in Safari or Edge, works with full editing features.
- Enable Desktop mode in Safari → a stable fallback while mobile apps are patched.
