GTM templates: inspect import status when an update goes missing

Simo Ahava’s 28 August guide explains the Status link in the Community Template Gallery. It shows imported GitHub commits and associated errors, helping template authors investigate missing updates.

Multi-source conversions: design the data reconciliation first

Google documents how an additional source can supplement Google-tag conversions. Its guide says conversions from the added source become biddable after 14 days.
