I am using non-Apple email, but Reminders / Goodtask for task.
Apple, of course, doesn't let us create Reminders from flagged emails that are from non-Apple accounts.
The way I've been going around this (when I need to have the info from email in my task) was to (1) copy the subject ;line of email (2) use "Print" functionality to get a PDF of email (3) send that PDF to Goodtask (4) paste the subject line.
Is there any way this could all be automated using Shortcuts ?
