After registering I wasn't even able to pay for a sub to check out their offering for myself.
English docs are lacking. I think they are focusing on fr and nl regions.
Support e-mail autoreply also only replies in those languages.
They are really small scale, ~2000 users by their own admission. Which is ok, but if you advertise a service, at least let people pay for it, so they can start using it, however janky it is.
