Bisq Linux app

I wonder why my bisq linux app is different that this one here ? :

In mine there in no learn section and private chats ? :

The top video and first image are from Bisq 2. The last image if from Bisq 1.

You can download both Bisq 1 and 2 from here: Bisq Downloads ‹ Bisq - A decentralized bitcoin exchange network

Bisq 2 has been updated since the video was made so it might look a little different.

Unfortunately now I have to remove the Bisq 1 to download a Bisq 2.
… which is not easy for me a new user of Linux.

In my opinion it would be better to explain it in details on the top of downloading page .

You don’t need to remove Bisq 1, you can use both in parallel.

Is there any chat with Bisq ?
I try to do the installation since few days and I have a lot of question .

The Bisq1 I aready has removed.

Yes there is a chat section in Bisq 2

Not for Bisq 1 (other than once and offer is taken or in mediation / arbitration)
