gkindex Thank you for the update, for the SSL as I mentioned it depends on the settings that you have as to whether the change in SSL certificate will cause any issues.
If you can let us know what settings that you have at Cloudflare we can then check this for you.
For the EPMV please can you confirm which dates you are comparing and I can take a look at this for you? I have taken a look at your data reports and can see that your EPMV and revenue have been growing.
For your query about setting up a new sub domain please can you open a new thread for this. Where possible it is best to keep the thread to questions that all relate to one topic and to keep the questions to only a few at a time. This helps us to be able to see all the questions that you have and not miss any. It also helps you as we are then able to answer the questions in the thread that you can then easily refer back to. Many thanks for your understanding with this
