Is this the same Phoenix wallet that is not allowing anyone from US to use it?

Yes, it seems so. I assume, they decided to duck the hail of bullets fired by US institutions recently. Of course, US citizens aren't happy about it when they're affected.
Another thing should be mentioned about this wallet, they are advertising as Lightning Network wallet, but you have to set max on-chain fee when receiving LN payments.
That means that sometimes you will have to pay additional fees when receiving LN payments.
Phoenix does automatic channel and inbound liquidity handling for users. When you create a LN invoice and you don't have enough inbound capacity to receive that payment, a new channel will be opened or an existing channels will have its inbound capacity extended (not sure, if you have a choice here). For this an on-chain transaction is required and fees as shown here:
https://phoenix.acinq.co/faq#what-are-the-fees.
It's good that you can set a limit here to avoid unpleasant surprises in times of high on-chain fee levels.
I find Phoenix' approach of comfort to handle capacity management a somewhat good compromise especially for a non-custodial Lightning wallet.
It's worth noting, that their FAQ is pretty good in my opinion. It will hardly help someone who doesn't have much clue about how Lightning works, but for those who do know the basics, it's pretty decent. A lot of questions one might have about Phoenix' specific handling of things are addressed as far as I see it.
So far I didn't have bad experience with Phoenix wallet, but I haven't used it extensively. A few payments that failed with Wallet of Satoshi for me did work easily with Phoenix wallet. I didn't care much why, just my particular experience.
