Recent Skype for Web update supports only Windows 10, macOS (and Chrome, Edge browsers only) So rest of the OS (e.g. Linux, Chrome OS) and browsers (e.g. Firefox, Opera) no longer has the access to Skype for Web! This is very disappointing from different aspects.

(Example-1) I need to access my Skype urgently on someone else's device but they're using the unsupported platform. So my work is undone. So lack of portability support will encourage me to switch to other messaging platforms.

(Example-2) Some people might feel complicated to use the Skype client for whatever reasons, and no access to the Web app will cause them switch to other messaging platforms.

I hope Skype team will understand. :)
