Yes, you have two ways to apply for rights shares.
Make sure you enter correct number, in your case 1308.
This is alright.
You can apply till midnight, but don’t leave it this late.
You sold your shares on 24th, you should be able to withdraw funds on 28th evening, once processed your funds will be transferred within 24 hours (Say you will have funds in your bank account by 29 evening) you will still have a day to apply for rights shares.
