Unable to add modules (android, IOS and etc.) with unity hub

Hi, i’ve got these weird issues. I’m using mac and i have installed Unity 2019.4.20f1 with Unity hub. When i go to installs in unity hub, select the installed version and add android module, it starts installing. When it finishes, i open a project and i cant change the build to android, it still says “install with unity hub”. Also in unity hub when i open the adding modules section, it still has the option to add android build, which means it hasnt installed.

Also i tried to download the latest 2020 official release with unity hub, and half the way installation failed saying “corrupted download file”. How can i solve this?

I just tried to install 2020.1.17f1, and it seemed to finish but once again, doesnt show up anywhere, theres only the earlier installed 2019.4.20f1 version

Same here with trying to update to 2019.4.21f1 (from 20f1). No clue what’s going on. No error message, nothing. It’s just not showing up in the end after lengthy installation.
