Check that the mobile number matches the father's or mother's number saved with the school,
and that the date of birth entered is the student's DOB, not the parent's.
Contact the school office if details need correction.
Ask the school admin to verify the student record has the correct father/mother mobile number.
The default app password is usually the father's registered mobile number.
Use the same parent mobile number. If multiple children are linked to your number,
the mobile app shows all children after login. On the web portal, you access the child
linked to the mobile + date of birth combination used at login.
