By running the below command, you give Zoom a read-only access to the CA certificates
from the host environment. flatpak override --user --filesystem=$GUIX_PROFILE:ro --filesystem=/gnu/store:ro us.zoom.Zoom There might still be more issues I am not yet aware of, but in general, with any of the solutions above,
all problems related to CA certificates with Guix should be solved. Next time, if I find a new type of issue and I can develop a workaround, I'll add the information here.
