Bluesound Pulse Mini (2017) limitations

Hi,

I have two Bluesound Node 2i that I'm happy with. I got an offer to buy an used Bluesound Pulse Mini from 2017 that would be a perfect complement for my patio :)

However, I understand that this is an old model, so I would like to know if there are any limitations regarding multiroom play with the Node 2i's or any other important issues. I mainly play through Tidal connect.

Thanks,
Dan
