DCA “Save in BTC” has just 6 countries

I recently heard about the new update which I think is pretty cool.

Unfortunately there are just a handfull of countries available for the Save Bitcoin option
– Belgium
– Czech
– Germany
– Netherlands
– Spain
– USA

Is their partner invity making these restrictions or is it coming from trezor?
makes no sense to have such a small amount of countries unlocked
