Yep. Crazy to lose such an important and key feature. Previously there was an issue also, though. I wasn't able to copy a Teams image and paste it into Whiteboard, but I could paste it from SNIP which was super-handy.
Whiteboard caused my computer to crash (randomly, but often) when sharing with students anyway. So, I started to use SHARED PowerPoints as a solution. If find that more useful when sharing with small groups of students.
