I’m having issues adding a miro board. Upon clicking “Add a Miro Board” in the Blocks tab, Google Chrome opens but to a blank page. I am logged into my Miro account in another tab.
I’ve also tried logging out of my Miro account prior to clicking “Add a Miro Board,” and Google Chrome opens a page that only displays “Not Authorized.”
Can someone advise how best to solve for this?
Hi there Oliver! I too ran into the Not Authorized page when invoking the “Add a Miro board”. I found that this issue only occurs when I try to invoke it via Airtable’s macOS app. However, if I invoke it via their web app, the issue no longer exists and I am able to add a Miro board.
Someone from Airtable might want to look into this issue if they haven’t already. I’ve shared the error log below.
Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://block--61-y-qg4-b0hzid-v8--qu78jbs.airtableblocks.com') does not match the recipient window's origin ('https://miro.com').

Similar to @Oliver_Monaco1 and @Maricris_Bonzo, I was stuck on a "Redirecting … " page when trying to add a Miro board.
Starting from the Airtable desktop app (on Windows), Add a Miro board opens a board picker link in a browser then causes the error.
Thanks @Maricris_Bonzo for suggesting starting from the browser rather than the desktop app. That works for me too.

I am still experiencing this issue three years later on the MacOS app.
