There are several reasons why a deposit might not be processed immediately:
Payment Methods: Payments that do not match the details stored in the Tipico account will not be accepted.
Credit Card: Payments with a credit card can only be made once the creidt card is verified. Verification is done through Jumio. When depositing with a credit card, click on <Card Verification>
Location/VPN: Payments cannot be successfully processed if you are not in your registered country or are using a VPN. Check this in your device settings and disable the VPN connection if necessary.
