More problems with whiteboard

So yesterday i create a post about my students cannot see what im typing,
Today i started my class and the whiteboard didnt work at all.
I had some whiteboards open, which i deleted all to trash. When i opened a new whiteboard page, it gave me the last whiteboard (that i trew away.) But when i doubleclick on the whiteboard its blank. When i start writing there and select the text to move it, it multiplies the text over and over..... i canceld my class because im not able to work like this... Does anyone have another solution? A whiteboard that i can use in combination with zoom or maybe a whole new working environment? Teams? Skype? Never worked with that programs but im open for sugestions!

Thanx!
