'Troubleshoot performance fluctuations and changes' help docs published for each campaign type

Google Ads published a set of ten new or reworked help documents on troubleshooting performance fluctuations and changes: a general guide plus per-campaign-type guides for Performance Max, Search, Display, Video, Shopping, App, Smart and Demand Gen, and a guided troubleshooter for Performance Max spend fluctuations. The general guide lists ten common causes and points to the Explanations feature.

Documents: Google Ads campaigns, Performance Max, Search, Display, Video, Shopping, App, Smart, Demand Gen and the Performance Max spend fluctuations troubleshooter. Barry Schwartz noted it was unclear whether every document is brand new or whether some existing pages were reworded.
