Conversations involving multiple participants, allowing collaboration and information sharing in Teams
I think this is another case of some dev lead thinking they have to make some change in order to still stay relevant. Too many "higher ups" and devs in companies nowadays just come up with updates just so they can look busy. If the system is working as needed and nobody is complaining there is no need to change it.
On a note of the changes: ANYTHING that forces a user to add more steps to what they do is not "simplified" and that's just by definition. Many of users have teams for part of a job ; so anything that distracts or slows down that employee more is not a good update.
Also when replaying to a particular conversation in a "team" there is no good reason to force the person into a "private" window and not be able to see the rest of the team's chatter.
Please tell whoever the dev op is in charge here to stop feeling like they need to do something to keep things moving even if its a bad update.
EDIT: also both ways provide to get rid of the "start a post" does not work ; no option to "use old version" exist under the profile icon. Pressing CTRL SHIFT N only brings up a whole new window to start a completely new chat.
