I have tangem card and I did use seed phrase option, I imported my ledger seed into tangem, thinking it's safe, thankfully didn't message their support so I assume I must be safe? I mean my funds are still there.
I just came to know about this issue yesterday and ranted on their discord for about two hours. I was disappointed with vulnerability itself — how can you record seed? Even literal hot wallets don't do that, and with their communications.
I am done with them and moving to trezor. Reminder for me to stick with tried, tested and reputed HW providers.
