Pageviews and Sessions in Journey are more than half less than in Google Analytics? +More!

Hi there, I'm new here and have few questions that no one have yet answer me or helped me to try and fix the journeys problems.

So, as the title states the page views and sessions in grow and journey are 50-60 % less and smaller than those in google analytics and I'm not sure why as the stats are coming from the same place??

I used the formula and saw that something isn't right as per the formula I should 3.4 from journey stats and 8.7 from the google analytics stats, but it show that I have only 0.7 rpm only coming in the stats.

Can someone help me or point to me how to help myself as after almost a month the numbers are not real at all, why I'm losing traffic and earnings ?

Also only the traffic from US is monetized at the moment,  (generally the most traffic is from us)  but the traffic from EU, Singapore or everywhere else is not monetized at all.

I would like the support to look at my site and help. - The site is “www.doggozila.com”

Hopefully someone can offer a direction to overcome these problems and focus only on publishing.
