Today I provided the client with additional explanations and screenshots, as I find it difficult to clearly consult beginners. But finally, Vladislav and I have come to an understanding and will continue to collaborate.
Also, a special thanks to the client for creating a separate personal project for me, as due to a technical failure of Freelancehunt, I received a reward for yesterday's project of 25 UAH instead of 25 USD (1033.28 UAH).
I recommend the client to other freelancers with a request not to overload him with deadlines on Google Ads theory and Google Analytics, as the person is just starting to launch Google Ads and figure out Google Analytics, Google Tag Manager, and cookie consent settings (Vladislav started using Google Ads and GA4 only three days ago).
