@gabrielluong how do you want thumbnails issues to get tracked? Just in the board, or through a label, or something else?

Most of the thumbnail issues would be fixed in AC. So, I think for tracking purposes we can put it in the tabs tray board as a stopgap.

This was fixed as part of mozilla-mobile/android-components#7352.

Hi @jonalmeida , noticed that on Fenix 79.0.1-beta.1 from 6/30 the screenshots are replaced with the placeholder icons after delete + undo
Is this the expected behaviour? please advise

[jonalmeida]

@AndiAJ yes, this is expected behaviour. We are deleting the thumbnails on the device.

We have a separate bug to figure out how to keep the thumbnail until after the undo toast is gone. 🙂
