Logging in appears simple until it refuses, at which point the reasons prove almost invariably from a same limited set.
The Normal Process
Launch the app or its web version, enter the sign-up mobile number with the correct country prefix, enter the password, and then clear the additional check enabled - fingerprint recognition or an OTP.
Account Controls Genuinely Worth Activating
Fingerprint login removes the risk to use a short password. Login alerts notify the owner when any unfamiliar device signs in. If two-step verification is made possible, activate it.
Eight Common Causes a An Access Attempt Does Not Work

One missing country code; one accidental space in the password field; one
outdated app build; cached login data; a lock triggered by too many OTP resends; a account registered on a site in the first place; ISP restrictions; and an actual platform block.
Working Down The List
Test each phone-number formats. Key the password into any notes field as a test to expose invisible characters. Reset stored cache, refresh from its first source, allow fifteen minutes following repeated OTP block, and confirm the domain on which the account genuinely lives.
Should None of It Helps
Write to support in a email channel with the account number, the approximate date of the most recent successful login, and the order numbers you hold. Save all message.
A Practical Step
Verify the URL ahead of every login. Fake pages are the principal cause of account theft in the sector, and our independent reference at
