Can anyone else confirm the issue?

[tomholub]

This error appears unrelated - looks like a Gmail error.

Any other errors? Any errors in background page? Anything to take a screen shot of when viewing the draft?

[tomholub]

I seem to be able to open the draft.

You may want to check if you are saving a plain text or rich text draft. Rich text doesn't work #3082

[limonte]

I'm saving regular drafts, here's the screencast:

That's correct. But for me, Gmail is opening its own drafts correctly, the issue happens only with FlowCrypt drafts. So, probably, we're changing/removing something Gmail depends on.

[tomholub]

You're right.

Gmail generally does gradual updates for new functionality. So you may have it, but I may not. Likely, the way we are doing it does not work well on the different / newer version of Gmail that loads for you, and would be something to look into.

For the record:

1. I can only reproduce this for my limon.monte@gmail.com account. For sweetalert2@gmail.com the issue is not reproducible.
2. The issue is reproducible even with the extension disabled, Gmail will fail to open a draft made by FlowCrypt even without the FlowCrypt extension.
