When I refresh my accounts, I'm not allowed to refresh them again for 4 or 5 hours.
However, if I have a typo in my MFA code, I have several accounts that will not be refreshed an cannot be refreshed for a very long time.
Since I tend to do this first thing every morning, it's unfortunately true that in my bleary state I tend to fat-finger a lot.
It would be very convenient if the software could detect a failure to connect, and allow for immediate retries.
