What is AdMob error TCF 7.8 for my Android App?

Question

On AdMob web site I just saw an error concerning an ad banner in my Android App (niveau de la version 2.0 du TCF de l'IAB) The error is 7.8 which means: TC string version field is neither 1 nor 2.

Only limited ads will be served. CMP should fix the TC string implementation errors.

What is it ?

The error is under this text:

Google will handle issues When these issues occur, Google will mitigate the problem, itself, when necessary and proceed with normal TCF handling.

But it's weird, since beginning of January my income have decrease a lot, is it link to GDPR ? What can I do ?

thanks

Google will handle this issue.

Google has announced that it will actively address issues with error codes starting from 7.X, including error 7.8. if you see the error 7.8 in AdSense or in AdMob just wait. Typically, the message should disappear on its own once the issue is resolved by Google.

So, I guess that you can ignore the warning and that Google will fix it
