Poshmark new account scam- I feel so dumb

I fell for a scam within the poshmark app today while setting up my new account. I received a message within the app stating that it was time to verify my new account that lead me through scanning a QR code and entering PayPal info (linked to checking account) and credit card. They quickly and successfully attempted a crypto paypal transaction that is pending. I feel so dumb.

I’ve since:
- changed all passwords and added 2factor authentication
- canceled credit card
- froze all credit
- notified and filed fraudulent claim with PayPal
- notified bank via email (closed today for Memorial Day) and requested to not process that specific PayPal transaction. Will call first thing in the morning to get human verification
- notified poshmark with screenshot of scam user message thread
- cleared history and website data on iPhone

Is there anything I’m missing that is important after such a dumb mistake I made?
