Hey @alfetopito , nice changes!
However, I have found the issue here: the banner remains to be displayed when I switch from GC to an unsupported network

I think, it would be great to hide this message when connected to an unsupported network.

Then, I think it would be nice to add a 'hover' effect to the banner (highlight links or so). WDYT?

[alfetopito]

@elena-zh should be fixed, please try again once the build finishes

Hey @alfetopito , great!

However, I have noticed that only in this PR I have started to see 'Hang in here..' message when switching back from an unsupported network to a supported one.

Please, follow these steps to reproduce the issue:

1. Connect a wallet to GC
2. Change to an aunsupported network
3. Change the networj to Ethereum --> you will see a hanging 'Hang in here' message

As for the hover effect, could we please change its color to orange as we do on the 'Profile' page for cards?

Thanks!

Hmmm, that's weird.
Locally everything is fine.
Trying it out in the PR link though I can reproduce it.
Will see what I can do.

[alfetopito]

In any way, that issue is definitely not related to the PR at hand and should be addressed separately.
I'll address your other comment regarding the orange in the link then proceed

@alfetopito , hm. I retested it in #502 PR, but it was not reproducible there. So I thought that it was related to the current PR.
But now I have retested it again in #502 pr, and now I'm able to reproduce it there. So I have created #514 issue for this.

LGTM now!

Merging as is, @fairlighteth feel free to post merge review

Looks mostly good to me. One thing I noticed is a slight overlap of the Appzi button:

But it's something I can address at some point.
