[2022] Unable to obtain more than 3 mounts?

Hi! I just tried to buy a mount of Reda and received an error indicating that I have the maximum number of mounts. This struck me as odd since inventory is unlimited and Origins allowed numerous mounts. If 3 is indeed the limit, is there a way to get rid of existing mounts so one might obtain a new one? If not, it would be helpful to inform players of the limit so they can be more selective in what they choose.
