If your bank branch has changed, you can update your details in the new e-filing portal by removing the old branch and adding the new one. While you might encounter a 'validation failed' message due to technical issues, simply click the revalidation button. Your account will appear as 'validation in progress' and should be completed shortly.

How long does it take for validation? When I add the new branch after removing the old one, it shows that validation has failed for technical issue and am asked to click revalidation button. Once it is done the account is shown in the added accont list but with a remarks that validation is in progress which is never completed.
