Incoming calls do still not show up when I have an active call on the other SIM

I posted this months ago and it is still not fixed (and the support was suboptimal, to say the least):

When I have an ongoing call on one SIM and a new call comes in for the other SIM then this call does not show up and is also not listed as missed call. The calling person hears a few peeps and then the line is cut like when you reject the call.

This is a serious problem.

I tried the default phone app and also the simple phone app from the f-droid store: both show the same problem.

It does not matter whether I use e-SIM or the physical SIM for the first call.

(unfortunately the original thread is closed now)
