But, if we open a web browser, login to AdWords, delete the kws with poor QS, change the match type, save, and then change the match type back again to its original form as uploaded via the API... the QS is OK or Great.
Anyone else experienced this?
We're assuming this is a bug related to the API and the relatively new QS column in AdWords but haven't seen any other posts reporting a similar issue.
As I say, if we add the same kws and their match types via a web browser in AdWords... no such QS problems.
Puzzled.
