Email forwarding to GSuite has been working fine since I set it up on Netlify weeks ago. However I thought it would be a good idea to increase the TTL on the MX and TXT records from my set up value of 5 seconds to the default value of 3600.
I created a new matching record for each entry with the new TTL of 3600 and then deleted the old entry. I quadruple checked everything was exactly the same as a screenshot of my original settings (attached).
The problem was I was then unable to receive email although I could still send them. 12 hours later and I could still not receive any emails.
To try and fix it I then changed back to the TTL of 5. That was 5 hours ago and I am still unable to receive emails.
How is this possible and what should I do to resolve?
