Side Scrollbar disappears frequently in the New Teams.

Disable new teams option is what I did for now sorry image in Portuguese

We all know about hovering the mouse pointer - that has been in place for several months now - but this is a NEW issue - the scrollbar no longer appears when you hover the mouse over the right hand side of the sidebar. This function has vanished; it simply doesn't work any more.

This is exactly the issue I am facing: the scrollbar disappears (see below for the steps to reproduce). But there appears to be a workaround (described below).

Workaround:

1. Press Ctrl + L -- this should shift the focus to the list of chats
2. Use the up arrow and down arrow keys to navigate up and down in the list.

Steps to reproduce in the desktop version:

Teams Version: 23335.232.2637.4844

Client version: 49/23113028724

0. Navigate to Teams.
1. In the left-side vertical ribbon (i.e., the left column ), click on the Chat icon.
2. In the top right corner of the Teams window, click on the "resize window" icon (or use the Windows Key + directional arrow to resize the Teams window).
3. As soon as the Teams window resizes, Teams will momentarily display the vertical scrollbar on the right side of the column listing all the chats.
4. After a second or so, the scrollbar disappears. That's the bug.

? How can this be 'by design'? It's an essential function! On my device it doesn't appear ever - at all - even if I start scrolling! And unless you have a touch screen you actually cannot scroll at all without the scrollbar, so how can you make it appear? It's an appalling mistake, or bug - whatever it is it needs to be fixed ASAP. Does Microsoft actually read any of these complaints and issues?

I am having the same issue. This is very annoying and it is compromising my work for the day. Microsoft needs to fix these bugs before they release these updates. This is not an update if things don't work.

Annoyed with Microsoft!
