Ubuntu – Android devices stopped showing up in Nautilus (Ubuntu 18.04)

When I connect my Android cellphone to my home PC it does not show up in Nautilus – a nice cellphone icon labeled Android should show up on the sidebar but only additional CD-ROM shows up. No success with a different cellphone and a camera. On My home PC the gmpt can access both the cellphone internal and additional memories but Nautilus cannot do that anymore.

When I connect the phone to my office lapton then it shows up in Nautilus – both Android and CD-ROM shows up. It works perfectly.

Both computers: the same Ubuntu version, the same software installed, the same configurations. Maybe I've messed up something on my home PC while learning Ubuntu?

On my home PC the mtp-detect returns:
