This is not a charge on your account but a ‘reservation' by the banking system, this is not from TIDAL and isn’t a charge. It is the banking system validating your card and the sum will be refunded. Reservations like this are common when using a new card as a way of the banking system checking your card is active.
Lastly, if you have multiple $2 sums on your account, this is most likely due to multiple submissions of your payment details. Once the authorization is complete, all verification fees will automatically be refunded.
