I asked, and recently several u cards and payment options have been completely halted.
These are the issuing channels (BIN) that everyone relies on, which are frequently being blocked or frozen by Visa or downstream institutions, and the cost of switching channels is becoming increasingly high and difficult to sustain.
Additionally, several payment settlement companies, such as bewildcard, have recently been rumored to have their boss involved in illegal operations, and employees being implicated in aiding and abetting crimes. Combined with the recent cases of cross-border payments being caught, they have all temporarily halted operations to mitigate risks.
