I've had a Flow that's been working flawlessly for months. When a new email arrives to a mailbox with "{NEW HIRE TRIGGER MESSAGE}" in the subject, it performs some actions and then deletes the email. The last attempted & successful run was 3 weeks ago. Last night, the email arrived into the inbox and just sat there. I tried re-sending the email to the mailbox this morning under Test conditions, with the same result. Nothing has changed with the Flow. Permissions to the mailbox show all green.
Is there something I should be checking? I need to have this up and running soon.
