So I changed the netlify hosting to another one tied to git for quicker updated as I test and I still see the same issue. 

I am seeing a weird not public URL issue even though I can navigate it no issue.

 

• Change the app URL to a publicly reachable one.

• If your app uses OAuth authentication: Add a publicly reachable redirect URI.

​@Jeff Prentice Totally not a modern developer here, but I have made enough apps work based upon Miro’s examples to notice that you’re missing code to tell Miro to initialize the button in the creation bar. I’ll let ChatGPT help he out here:

You're right to suspect that some app initialization step is missing, especially if the app icon is not appearing in the Miro toolbar. Based on what you've shared, here’s what’s likely missing:

Problem: App is not registering an icon in the Miro creation toolbar

In Miro's Web SDK v2, just including the SDK and calling miro.onReady() is not enough to get your app's icon to appear in the creation toolbar. The toolbar button must be explicitly registered using miro.board.ui.on() with the correct event, or through your app's manifest.json.
