Just saying, you can't renew the bank account details yet, it is locked for all accounts lol.
For current status(midnight), just do this.
Step 1,
Open a new Incognito windows.
If you don't wanna do this, just open
https://bpn.hasil.gov.my/ , click on the padlock icon on the left of address bar, click on cookies, spam click on remove, and enter again.
Step 2, If loading >3 seconds, it means it failed for processing, and you need to...
Step 3,
Click F5 if you are submitting a new request for NO RECORD in the system, and the server will NOT let you CETAK the maklumat after you submit to the server and asking you wanna yes for create account, no to exit, and CETAK for check the info.
If you lulus and wanna create a new account, just CLICK AGAIN on the button(SETERUS) instead of F5 for filling the security question, answer and password.
If hang forever, start from step one.
Also please expect that, you will failed lot of time on captcha for the new request submitting, just f5 again if hang, and wait for dialog pop-out telling wrong captcha, just refill the captcha, verify again.
As this required a full page loaded to pop-out a windows telling you to tick on it, so it required a full page loaded before you can hantar your maklumat, which is last step that allow you to F5, huray~
Hope this helps in midnight.

i find no place to create new account.
also just done for my parent but status show diterima, no lulus or fail.
