I used the desktop Bisq client years ago close to when it first came out, I think. Love seeing continued development. Will be downloading this!
If you are going to install it on your mobile phone, please take into account that there are two apps to trade on Bisq2, namely Bisq Easy and Bisq Connect.
If your phone is one of the latest models, you might want to consider using Bisq Easy; otherwise, Bisq Connect could be the better option.
More on the difference between these two
can be found here.
