WebPlugin error. Uncaught Error: processCommandFromIFrame:: iframe channel not found
Hi, I’ve created a simple test plugin using one of the examples app as a scaffolding. The web plugin allows the user to roll a number of random dice. This is the installation link for the  app (still in development of course) https://miro.com/oauth/authorize/?response_type=token&client_id=3074457350145576827&redirect_uri=https://miro-rory-story-cubes-prod.herokuapp.com/auth-success.htmlThe app seems to work fine most of the time but for some users and on some teams, it works just once. After first usage we get this error:Uncaught Error: processCommandFromIFrame:: iframe channel not found, plugin = 3074457350145576827, cmd = .board.viewport.getViewportIf we reload the board and use it, it works the first time and triggers the error from then on.The issue seems to be consistent for certain combination of user/team/browser. EgI can use it on Team A, always	I can use it on Team B, always, using firefox	I can use it on Team B, only once, using chrome	A teamamate can use it on Team B
