Had 24 pages of items stored in the user account on Joplin Cloud. Selected the option to delete all. After confirmation there was a long pause and then there was an nginx Gateway Time-out. Logging back in revealed 10 pages of items had been deleted. Delete requested again, and again it timed out. Logged in again and deleted again, timed out again, but items were eventually cleared using this process.
Ideally the deletion would complete in the time allowed.
