Dual Sim Stopped Working

[Hannah352]

I have a dual sim in for a few weeks now with no issues.

Since I've done the latest android update (One UI 4), my 2nd sim isn't even detected. I've tried all the usual things (restarting, cleaning sim card etc) but can't work it out. Please help 😫

I never got mind to work, had it in a different phone instead
