If I have a credit balance in my Google AppEngine dashboard for a particular Open Data Kit Aggregate instance which is well within its quota limits, why am I getting this message??
"AppEngine Application Problem. A problem has occurred that prevents your AppEngine application from responding. Your application may have exceeded its per-minute or daily usage quotas. Please visit your application dashboard at Google AppEngine. The Billing Status section will indicate what daily or per-minute usage limits your application has exceeded...If neither of those indicate any problems, then your application's Logs may; these are reachable from the dashboard via the Logs link on the left sidebar under the Main heading."
I have search the dashboard far and wide and don't see ANY red flags whatsoever relating to logs, or exceeding any quota limits. I added a new credit card and paid a $3 outstanding bill by making a payment for $20. Hence a $17 credit balance. About to give up.
