IME the Whirlpool desktop client is mandatory if you want your coins to remix. Your first mix is given priority in the system, subsequent mixes are not, and the mobile app does a poor job of registering coins for remixing.
Also, there's different tiers of pools, each that break up your coins into a certain fixed amount. I find that having a lot of tiny amounts is hard to manage, so I prefer the larger tiers.
The article also does not mention the 'doxxic' change that is produced from the initial mix, which I think is also important to consider.

Whirlpool bitcoin mixing breaks deterministic links to past transactions and provides forward-looking anonymity. This article demonstrates the easiest way to Whirlpool your bitcoin so that you can take steps to preserve the censorship-resistant and permissionless attributes of Bitcoin.
Some of the privacy-enhancing tools built into Samourai Wallet include:

  • Stonewall, a post-mix spending tool that breaks on-chain heuristics
  • Stonewallx2, a post-mix spending tool that looks identical to Stonewall on-chain but is actually made with two peers
  • Stowaway, a post-mix spending tool that obfuscates the amount being spent
  • Ricochet, a post-mix spending tool that adds additional hops between the final payment destination
  • Advanced coin control

Here's the Tweet kicking off the (long) Twitter thread announcing this article and describing Whirlpool further:
1/25 #Bitcoin on-chain privacy is becoming increasingly important as govts trend toward tyranny, as money gets weaponized, and as data breaches become more targeted.
This @BitcoinMagazine article covers using @SamouraiWallet's Whirlpool on mobile.
