Having an issue with syncing emails from a linked Google account. When trying to retrieve messages using the ‘any\_email’ filter, it seems as though casing matters. For example if the email is ‘Test.Test@email.com’ and we use ‘test.test@email.com’ for any\_email in the request, we won’t get back any of the emails with the exception of emails sent to that address where the user typed the email as ‘test.test@email’. Is this an issue or expected behavior for retrieving emails from a google account? ---
