All iPads or just some don't have Chrome installed? Did you grab enough licenses and deployed the scope to the desired group?

Its on all ipads and jes I have more licenses than ipads and just one group of them.

Oh is the app icon hidden?

There is nothing visible on the hidden feature. If looking in "Apps" its also not showing up. 

Under Restrictions->Media Content do you use an age filter for apps? Google Chrome is a 17+ app.

or

do you have a profile with a Blocklist?

Sorry for my delay. There is a filter for web contence for kids. But there is no restrictions for apps. On older ipad with IOS 16.7.10 chrome shows up in the app list, but not on the home screen layout. On IOS 18.2.1 it doesn't show uo anywhere. By the way it's not the only app missing.

Disable all profiles (except for Wifi) and enable the profiles one by one to find out wicht profile causes this behaviour (I hope you have 1 payload per profile). When you found out which is the problem profile, you can troubleshoot that profile (I assume that the app shows up when all profiles are disabled).

LOL, I found the mistake.... There was a part in the profile, which controles the media content. And the apps were set to 4+ instead of all apps.

So it was: Under Restrictions->Media Content do you use an age filter for apps? Google Chrome is a 17+ app.

Exactly, I didn't see it at first time.
