First started my phone abroad, and now some features are blocked

[BlowItUp null]

I was working abroad recently and while i was there i got a new Galaxy S9 (im from germany and the phone is too but I started it first abroad).
Now that i'm back some of the features on the device, that where unavailable in the country i was working in, remain blocked.

I use the maps timeline and location sharing a lot, and have done so before, but on the new phone there is no maps timeline, and whenever I open location sharing it said it is unavailable in my country (which it isn't as I can still use it from my other devices).
However there was a download feature available in the YouTube app, which has since disappeared and the videos I downloaded are unavailable in my home region.

Is there any way to change the localization of android without resetting it? I have already tried all the available location settings that I found in the Google app but nothing changed.

It may have locked to the region it was first activated in. If that's the case, even reflashing the ROM might not reset it.

Try reflashing the German ROM to it using ODIN and the report back.
