Adsense launches a new and improved Reports page so that you can get valuable information about the performance of your account faster and easier. At least that's how they officially announce it on their platform.
What will happen
As of August 25, 2020 Google Adsense has started to implement a new reporting platform for all publishers. The launch has been in phases, in some cases the new reports have been delayed but, as updates arrive, they will be presented in the accounts of the associates. Once the account is updated, the new page will be enabled automatically.
For those who initially cannot adapt to the changes, you can switch between the old and new experience at any time by clicking on the switch located at the upper end of the site.
