I use Thunderbird (64bit, 128.0) to check my gmail account. When composing an email I can not choose google drive when sending an attachment. I've tried installing the google drive desktop app on my computer but once selecting the file I want to send, I get an error that I don't have permission to access that file. "Sending of the message failed. There was an error attaching Expenses 2020.gsheet. Please check that you have access to the file." It is a file I own. I can however, send a pdf file that was stored in my google drive. How do I send google drive files using thunderbird email? Thanks in advance for the help. Todd
