I finally got the update and, while I need to try and keep this constructive, as a daily user of the Windows app, this update is a massive step backwards. I appreciate that you are trying to close a gap with Miro but we already have Miro and I do not use it for Whiteboarding. I think maybe you should split out this new Teams/Miro thing and allow power users to revert to the former app. The removal of copy/paste has completely broken the app. The pen menu is a huge step backwords.
Some time back I read this article and pondered switching inking to OneNote and today I have been forced to do so because this Whiteboard version is no longer usable. I am sorry to be so brutal but this article explains what needed to happen to the old Whiteboard to make it better....not what has been done to it.
