Hello, I’m Gennadii. 
I’ve been using Miro for a long time. 
I’ve used Miro from various devices. iPad + Macbook. 
Today I couldn’t use properly miro using app for iPad. 
I started writing using iPencil and my sentences disappeared. But I can see then on my Mac. Sounds strange but it was like that. 
and I’ve tried to restart my iPad and redownload miro app, it didn’t help at all. 
When I zoomed in - I can see all my writing, but when I zoomed out (5-4%), suddenly some letters started disappearing. 
What can I do to solve the problem?

You can see the problem in the pictures below
