Can't download or install plugins (infinite loop)

Hello guys, first time here. Been using sketchup for a bit and now need a cleanup plugin.

I’m having an issue with accessing the extension warehouse -specifically downloading plugins.
The following is happening:

  1. I find the plugin
  2. Get prompted to login
  3. Authenticate with my gmail account (i’ve tried a few)
  4. I get kicked back to the plugin page and I am logged in
  5. I click download and…
  6. Arrive back on the extension warehome homepage but logged out.

This goes on and on. I have tried:

  1. Chrome
  2. Safari
  3. Clearing cookies
  4. Different Google accounts
  5. Installing from inside the app.

Really not sure what to do? Help much appreciated.
