I ran into the issue with the latest version, the issue i was noticing is locationsharinglib requires beautifulsoup4 (version 4.6.0) but 4.6.3 is installed.
I found this out trying to manually create the cookie by running SSH and doing the following:
get-maps-cookies -e EMAIL -p PASSWORD -c FILENAME
which i get an error saying the locationsharinglib requires beautifulsoup4 v==4.6.0 but sees v==4.6.3 and fails.
what i did was run ‘pip install locationsharinglib’
which uninstalled and reinstalled beautifulsoup4 and put the version to 4.6.0
than reran the get-maps-cookies, which than showed the device in the recently used under google. deleted the cookie and restarted hassio, which updated the beautifulsoup4 to 4.6.3 and my google account still authenticated.
This worked for me, but i don’t know if it will for anyone else, and of course i take no responsibility for any issues this may cause
