I want to be able to open a PDF, when in Google Classroom NOT in an assignment, with squid premium. Squid is not an option in the "open".
In google classroom, when you have a pdf attached, I should be able to open with squid or connect to squid!
We 100% agree! Unfortunately, this is not something we have control over. We have provided feedback to the Google Classroom team to make it easier to allow users to use third party apps to open PDFs (rather than just using the Google Drive PDF Viewer).
Please contact Google Classroom support and let them know you want it to work better with Squid!
