Hi Regie,
And thanks for your response. Yes, for sure, saving a picture to computer and then uploading the same will work just fine. The trouble is that when common users as myself use Teams, we want things to go quick, with minimum amount of clicks and tricks. Therefore
I find it completely obvious that ctrl+c followed by ctrl+v should work just fine when pasting something quick in Wiki tab, without the risk of things "magically" disappear from my Team-view...
However it seems to be some program bug that makes the pasted picture visible at first, and makes it disappear after a few seconds or after clicking on the picture. I opened the Team in Sharepoint, and there I see the added picture under Wiki-content. I
don´t understand why the picture sometimes shows, and sometimes disappears. It gives a feeling of uncertainty that I don´t like. Hopefully this will improve over time.
And again, thanks for your answer!
