Quick note that this behavior is occurring via the Miro app.

@KelK - Has this also been reported to Miro support?

I have to ask as it is a real mixed-bag as to who reads the Do I need to contact the Miro Support team or ask the community? post and who does not:

Thanks. I’ve now done that. It makes the app fairly useless, so hopefully they’ll fix it soon.

Thanks for submitting the ticket to Miro support, @KelK - this does appear to be acting rather buggy.
It would also help others on this forum if you could update this post with what the support team tells you - thanks in advance!
