Tab groups on Android keep disappearing

I have multiple tab groups that I frequently use in the Brave browser. I have them set up to sync to my desktop as well. A single group will disappear from my list of tab groups on Android at random. I have no idea what causes it or how to replicate the problem.

In order to see them again, I have to ungroup and recreate the tab group using my desktop, which is a giant pain. I haven’t lost access to any of them on my desktop, but they are no longer visible on Android.

Brave version PC:
v 1.78.97

Brave version Android:
v 1.77.101, Chromium 135.0.7049.115

Operating System:
Android 15; Build/AP3A.240905.015.A2

Phone:
Galaxy S24+

@obliged can you update to 1.78.99 and let me know if the issue persists?

It has indeed occurred again after updating to 1.78.99.
