I can share some firstt classic "idiot user" experience I had.

 When I created the Poll for the group, I noticed I was redirected to another tab for it but didn't quite get that I had to share it to the group. I thought it was already being shared on the chat.

Maybe you can include an extra button or step to share it to the group chat during the creation flow. 

 great feedback, I think making share to chat as last step after poasting or creating a poll is the way to go. 

 Desktop works fine 
Does not detect Amber or Bunker on mobile. 

Also it asks me to to join a chachi chat twice on 0xchat. I gave up for now trying to get it to work on mobile.  

 You don't have a browser signer installed? You should consider Nos2x. It has extensions available for both Firefox browsers, and Chromium browsers. However, most mobile chromium browsers disable extensions. But Kiwi Browser does allow Chrome extensions so you can use Nos2x with that browser. These extensions are very handy for signing nostr requests while browsing.  

 Incorrect 

I have Nos2x installed on desktop (this worked and can message on chachi)✅

I have both nsec. app and Amber installed on mobile. Chachi does not recognize any of these remote signers, again on mobile. Therefore, I cannot use Chachi on mobile. ❌ 

 What are you talking about? Everything I said is correct. I was suggesting that you install a browser signer that can be used while browsing, as an alternative to sites that don't support Amber. In order to use Amber or nsec.app for web apps, those apps need to support bunker, or provide a nostr connect string that you can use to link to Amber or nsec. Without that compatibility, you're not going to be able to use Amber or nsec. Browser signers are your only option.  

 OK so no Amber support yet. All good I'll just keep using my Nos2x like I have been using for years now. 

Hope they get mobile support soon that'd be cool 

 If you use any Firefox browser, you can use Nos2x right now. But since Kiwi Browser is the only mobile browser that supports extensions, that's your only other alternative, assuming you're using Android. Kiwi is a really nice open source browser focused on privacy, and its support for chrome extensions is a stand-out feature. Something to consider. If you use iOS, j believe there's a Nos2x-like extension specifically for Apple devices.  

 I have the same problem Claudio,
In the search bar it would not search any group I tried to search for 

I updated (after needing to update zap store)
and still had the same issue. 

I went to the desktop to login (to chachi), then join the group, now I'm in. But, in the video shown below👇, it still says in 0xchat I'm not in the group, but it is shown above that I joined earlier. 🤷‍♂️ seems like a 0xchat issue but idk

 I think the issue is caused by not fetching the group members list. You can try clicking “Join Group” or viewing the group information page on the top right button. It will fetch the group members list. 

 Thank you I'll try. Didn't want to confuse my relays with possibly the same npub
