Missing Openstreetmap Copyrigth Message on Mobile

I made an APP with the Appinventor, in the browser window the copyrigth line is visible in the lower part, when I create an APK file and install it on the cell phone the line is not visible. Is this only the case for me?
It is a map window on a larger display.
My operating system is Android 10 on an Honor View 10 cell phone.

Best regards Rudi

This is known and a fix is pending for the next release.

Thanks for the answer.
