Don't panic. While the RBI recently mandated that banks report data to bureaus four times a month (on the 9th, 16th, 23rd, and last day of the month), the bureaus still need time to process and update that data on their end.
Fold displays exactly what the bureau currently has on file. If you just made a payment, it will likely be captured in the bank's next reporting batch and will reflect during your next monthly refresh on the Fold app.
