Text displays as question marks on whiteboard

[PeggyMac]

We are using whiteboard to brainstorm ideas and I can read the text as I type but when I click away the text turns into question marks. About 1/3 of the people collaborating are seeing the question marks. I've checked that I'm using the same version of others. I'm on Mac OS version: 13.4.1 (22F82). Any suggestions?

HI @PeggyMac  can you share the text in replies (not include personal information), then we can take a try.
