Trying to upload a sketch in our teen coding club, today I'm getting this error.

I bought the Chrome extension a while ago, then cancelled the subscription, and have been unable to find any way to reactivate it. I presume this is related. How do I re-enable the subscription?


Hi @neale,

Can you please try going into chrome://extensions and deleting the Chrome app, and then re-installing it via the Chrome Web store.

Just to double check, do you have have firewalls or ad blockers enabled? The new licensing check requires access to https://www.googleapis.com
