Credit card frozen over a small fare adjustment, then unblocked

[VN] Revolut Ultra credit card frozen due to $0.23 Grab fare re-adjustment I’m an Aussie living in Vietnam. Revolut detected a tiny fare re-adjustment by the Grab ride-share app as “potential fraud”. Submitted the documents required to unfreeze the card but no idea when it’ll be reviewed. Anyone else dealt with this? I can still use my debit card, but prefer to use the CC for extra RevPoints. $0.23 😭 UPDATE: Card just got unblocked. Resolved in under 24hrs 👍🏻
