Authentication and cookies issue for embedded docs (draw.io, google doc-s, figma jam)

Hey folks! :waving_hand:

I’ve embedded a private draw.io diagram in my doc using Embed(). Works great on desktop — I get the login screen and everything loads fine. But on iPhone (Coda app), when I tap “Authorize”, I get a “Allow pop-ups” message, even though pop-ups are allowed in Safari settings. Tried using Chrome too, but no luck — just stuck on cookie errors.

The same situation with embedded Figma Jam file and Google Doc - cannot authenticate on mobile.

Anyone found a way to make auth-required embeds (like draw.io or similar) work on mobile? It is a big thing, as company I work with do not allow public sharing of docs

Thanks in advance!
