List of supported browsers
https://docs.sdl.com/791942/661831/sdl-tridion-sites-9-1-prerequisites/content-manager-explorer-prerequisites
The following is stated In the section on:
"Updating supported browser versions"
" The list of supported web browser versions was known and tested at the time of release. However, new web browser versions may have been released since that time that are also supported but have not been subjected to testing."
We are not able to list or describe any potential issues on when using future browsers
If an issue is encountered on an unlisted future version of a browser our recommendation is to revert back to a browser in the list of supported browsers.
If issue still occur then raise a case.
