This has been happening for while now.
I have some defined connections in Configure > Connections > Define Connections - under folder "Imported Fixed Users".
There is a little list at the bottom that you can open with a little downside triangle and normally it opens:
- Imported Fixed users > my defined connections
- Imported History
- Recent >
-----------------
- Other...
- Disconnect

The problem is - every day, maybe more than once a day - the menu above the line disappears. Only Other and Disconnect is left.
Of course when I go open the Defined Connections and re-save them, it goes back. But it's annoying.

That's odd. We'll investigate.

I found out a way to reproduce this.
I run Win 10 and use Remote Desktop to connect to Windows Server 2016 (don't know if these specifics matter though) and the Remote Desktop is on my extended monitor (different resolution). When I drag the Remote Desktop window to the primary display and make it fullscreen (everything flickers and the resolution is adjusted automatically) - THEN the connections are GONE!

Very easy to reproduce this bug.

As I said, it has something to do with the resizing/resolution change between dragging the Remote Desktop between monitors.
Annoying as ....
Every ... day, more than once
