Description of the issue:
About 1-2 months ago, all my grouped tabs on my mobile Android disappeared. I didn’t delete the tabs or anything, just opened up the browser to nothing and nothing in recent tabs. I got over it and created new grouped tabs. Today I was on the browser, exited, reopened to see all my old grouped tabs that disappeared but non of my current ones. I had important stuff I was doing and need to current grouped tabs back.
