As I have been saying for a while Google, Amazon, Facebook, all these companies are on the decline. We have allowed them to become so big that they don't fall fast but it's very apparent that they would have been disrupted if they were normal sized like companies were in the past.
Ad setup doesn't work, you are hitting random errors on setting up API calls, basic UX and non-functional pixel setups, some weird limits or even plain unresponsive pages.
