My Google Ad Account Optimisation score is affected by a Google Tag issue. How can I fix this?

If you are opening your Google Ad account to be informed that you have Google Tag issues that are affecting your optimisation score, you take a screenshot of the message and send this to Simprosys Google Shopping Feed support team. 

They will be able to check whether your tags have been implemented correctly and advise how to fix.

They may tell you to dismiss this issue because they implement the tag onto all pages and therefore you may be able to dismiss the message. You can also check whether tags firing across website using the tag assistant extension.
