It's keystone. I was using app on cellphone, watch only to see the balance.
But, WTF, I've just checked again, and now it's right, I can see the balance all OK. (I was refreshing it all day yesterday and today too, no ideia why it's right now; I checked it before starting the post here);
It looks like it was a bug or something and the app had a delay... no idea.
That's probably a bug in their app there is someone on Reddit who has a similar issue but he made the transaction from Coinbase to Keystone but according to him, it does not show any TXID on the Keystone transaction history. No update from him so I don't know if he already fixed the issue.
Here's the Reddit post that I'm talking about below.
