I have an issue with Google drive & calendar and
also OneDrive using Opera browser.
Current version: 98.0.4759.15 (issues since January at least)

Have reported this as a bug today.

Since quite some time now, at least since January I have not been able to:

add attachments to my calendar posts (calendar.google.com), it's not connecting with my Google Drive.
able to upload folders to drive.google.com.

I have updated to newer browser versions throughout, but this issue still remains, no blockers active, cleaned cache and whatnot, all good from my end. Doesn't work on either WIN 10 or WIN 11. Tried different computers to no avail.

FYI: Works as it should with Firefox & Chrome.

Attachments in Google calendar posts:
Trying to add a document or image in a calendar post , I only get a popup with a spinning icon (normally this popup is the connection to Google Drive & also giving options to upload from computer.)

Trying to upload folders from computer to Google drive:
Only getting error message: File not found.
(Individual files works fine though.)

Addition!
Yesterday I discovered I cannot upload Folders from computer to Microsofts Onedrive either. Onedrive errror: Something went wrong try again.

Halp!
