@deeppandya do you know when the crash was happening? Visiting websites? Interacting with rewards? Interacting with UI? We usually try adding any crash fixes into the release notes so need some context.

@kjozwiak these logs are from play store. So it may not crash for us. There may be some edge cases so I added a fix to avoid it as well.

[deeppandya]

There was one minor issue on some devices, when you open-close brave stats, it used to crash.

Thanks @deeppandya, so something along the lines of the following should work for the release notes?

- Fixed crash when opening and closing Brave stats in certain cases
