When I create a meeting in Google Meet and start a new activity with Miro the students on the mobile phone app of Google Meet are shown a prompt that they cannot join the activity. And when going into the options menu it states that the installed addon is unavailable. Also, it does not work when using the mobile phone browser as it will allow them to join the activity but will only allow them to move the screen and leave comments they are unable to draw on the whiteboard.

This does not affect any of the account when they are using a desktop computer, the main issue for me is that all my students do not have desktop computers and really only have cell phones. Is there any way to force this functionality so it can be used on the mobile Google Meet App or is there another whiteboard app that can work with it. 

Most searches show Jamboard had what I am looking for but it has been discontinued. Any help to solve this issue or alternative applications would be much appreciated.
