Change of advertising icons

Good morning everyone
This morning I noticed that the icons for ads in Codelar have changed in color and shape
And when I want to add the advertising identification number for Admob, the place to paste the advertising symbol does not appear as shown in the attached image
Thank you for informing me in this regard. Is it related to me alone or has there been a change in Codelar?

Please read, you will have to migrate to Google Ad Manager

and components changes in 1.5.4
