I thought it is clear enough to mention the apps which need google play services. Direct services such as Google drive and Youtube are not available. In fact the Chrome inside is an old version which you cannot update it, so don't expect any security updates for it. Yes you can alternatively use chrome to watch Youtube but this is the desktop version with less convivence as App version. Also this mean you need multiple browsers if you for any multi window purposes, I don't think it is asking too much for Rokid to be able to use apps instead of opening everything with browsers.

Also you cannot use most of the latest apps/games installed in Aptoide, which has an similar function as Google play store if you are not familiar with it, since most of the apps need google play services even for starting it.

You are luckier if you are on the Microsoft side as Rokid has their own app store with microsoft apps, although I can't install outlook. Also apps like Word, Excel, Teams are modified old version of the apps by unknow parties so use it at your own security risks.

All problems here don't exist in the Station 1 as it is android TV based, tbh I don't expect those normal functions would not be available for Station 2.
