"Upgrade Next" returns error
I could not find a similar issue, but I haven't been able to use the "Upgrade Next" feature to work since about a week after the reviewing rework on October 31st. I can't remember if I used it before or after the maintenance period on one that went through shortly after it came back up, but since that one went through, it gives me an error.
I see the above image like normal. Then it takes me to this:
Error text reads "Unable to Upgrade. (E2)". Subsequent times hitting the button just loops that message. I figured once something went through with an upgrade, it might reset, but that did not happen (I held one that was the next undecided and in queue to sort of pick which one got the upgrade).
