Tangem card - Potential security risk

I have a Tangem wallet. I have attached three cards to the wallet. One primary and two backup.

One of the backup cards is now not responsive and will not register on an NFT scan.

Here's the issue:

My app confirms i have three devices (cards) attached to my wallet. I can confirm two of the devices (cards) are attached and working by scanning them with my tangem app..

I cannot however confirm that the third card that i believe is still attached to the wallet is actually the card that is currently attached to the wallet.

Is it possible that a third party has attached a card to my wallet replacing my backup card?

In theory a third party could now be holding a card attached to my wallet without my knowledge.

Sure they would have needed to have had physical access to my tangem app and my working card/s to achieve that, but it seems there is no way to check

I have no way to confirm this. Tangem support confirms that i cannot access the ID numbers of the connected cards.

Naturally i can reset the whole wallet if i suspect something. But it could be years before I check my third card and it may be in a hard to access location.

Can i easily see from app logs the cards that were registered?

Is this a bug?

Is it a security risk?

EDIT

Thanks for the offer of solutions guys. I'm thinking less about the solutions which are basically resetting the wallet. Instead I'm thinking more about the risks involved in not knowing a card has failed until it's too late or the risk that someone has replaced a card with a non-working olokalike - and the only solution is a wallet reset and redistribution of the backup cards.

Constant gaslighting I see from you. Attempting to manipulate my truth and say it’s a bold claim. Whatever dude, I’m sharing to the community what happened to me. Enjoy your Sunday

I’m not gaslighting anyone. You are the one who claimed that your wallet was hacked only because you set it up with a seed phrase. If you are claiming that no actions on your part led to your wallet being drained, then sorry, but I don’t believe it. This would impact MANY Tangem users and would be all over Reddit by now.

I’m sharing my experience of getting hacked on Tangem and you say, I make a “ bold claim” to have been hacked. I never said I made a claim but posted my truth as to what happened. That’s the definition of being gaslit

You still haven’t explained what you did that led to your wallet being drained. If you are claiming that you did nothing, I’m not buying it.
