THis is what happened.
The time when i Deposit the money from maya bank to 1win, I did not notices that the wallet app is partially under maintenance.
Partially, it is working for maya to maya or online payment via online shopping. but the online banking from maya to other banks are down.
The money was sent and deducted to my wallet but not credited to the casino realtime. That was the main reason why they need to process my payment and credit it manually.
That was the first time happeend to me and mostly my deposit get to my wallet in less than a minute.
You were well this time but it's a valuable lesson for you without any cost paid. You must learn from this and must be more careful next times.
Wallet apps can be under maintenance, but you don't know what's happening behind the scene and in bad situation, they can upgrade their app with considerable changes including receiving addresses and so on. It can affect your transactions too and it's similar issue with upgrades on centralized platforms. It does not mean that if you send your fund to a receiving address that was used previously on a centralized platform, you will receive it in your account.
Centralized platforms can make big upgrades, migrations of their wallets so your fund can be lost. You can ask for support but it's not comfortable experience and you must afford to lose your fund.
