We are currently encountering problems to successfully update the Optimization Goal for campaigns that are using custom bids. When this happen you will receive a notice on the top right of the platform
this notice will appear after a while as the error do not occur on real time.
Not all the edits of Optimization Goal fails, only some combinations.
To avoid this problem you can:
- switch your bid on Automatic
- set your new optimization goal
- switch back your bid on custom with the desired value
We are working on two different fronts, we are trying to make the error real time or almost real time while another team is working to fix the cause of the issue.
