Hi there,
We ran into this problem when trying to update campaigns. Following the documentation on common errors I had to post this on this Forum, because we retried many times and some tries are successful but others keep failing.
Some background info: This problem started on April 15th. We try to update campaigns/adgroups for this account etc. every 2 hours. This worked allright for a few months, but now it crashes regularly on an Unexpected Internal API Error without further information.
I was hoping someone here can help us find what's going wrong. If you need more information from me to investigate this issue further just ask!
Best regards!
