Transactions, A/C balance take a lot of time to get updated

Transactions made with Jupiter money app take a lot of time to get updated , this actually isnt the main problem , the main problem here is along with the transactions even the account balances take a lot of time to get updated .I made an self transfer of some amount to my Jupiter account from my 2nd bank and it took whole 3 minute for the balance to get updated and i was unable to pay a bill at that point of time.
