New smartphone: I am worried that TC is not working properly.

[Doomnometron]

Hello,

I started using a new smartphone a few days ago and “miss” the many entries in various apps in TC. According to my technical understanding, these entries only appear after the app has called up the respective URL.
However, advertising (e.g. optimizely.com) and analytics entries (e.g. crashlytics.com or statcounter.com) are also missing and that makes me a bit suspicious.

Sorry for the large screenshots. These show the URLs collected by TC in two example apps (WhatsApp and BahnBonus) and their URLs collected over 2+ years.

And now the two identical apps after setup (so they have already been started several times while TC was already running) on the new smartphone.

Please confirm my understanding that the list of URLs will gradually build up and expand and TC is working as expected. Thank you very much and have a nice Sunday!
