Message "Unsupported Browser" for internal browser view (for some links)
I have MindManager 21. I have not used it for half a year, and am now creating a new mind map.
I have attached web links to some items in my map. For some links, but not others, whern I try to view them in the internal browser, it shows a message "Unsupported Browser. Office uses new browser technology and works best in the latest browsers. Please upgrade your browser."
When I open the link I get to a MS page about "Which browsers work with Microsoft 365 for the web and Microsoft 365 Add-ins"
I am lost and don't know what to do.
