How to distinguish a real Google Ads conversion-tracking problem from a period with no recent qualifying conversions.
Check the conversion action
Make sure the action exists and the intended action is primary where appropriate.
Verify the event
Use a real or controlled test journey to confirm the purchase or lead event fires.
Confirm account mapping
A valid event sent to the wrong Ads account does not solve the reporting problem.
Interpret the warning carefully
The warning can describe a lack of recent activity rather than a broken tag.
Final thought
The useful approach is to isolate the technical layer responsible for the problem, change one thing at a time and validate the real user flow.
