When trying to clear an existing PriceExtensionPriceUnit it won’t update. According to the API reference NONE is used to clear the unit, but this is not the case.
The same behaviour can be seen in the Google Ads interface. After changing and saving the existing PriceExtensionPriceUnit (see image) to “No units”. The unit will still be ”Per hour” after refreshing the page.
Is this expected behavior?
