Bangkok Bank Account Dilema

I am one of those who open a bkb account about 4 years ago using agent in Pattaya via tourist visa. My account survive all the purging even until now. The problem is I just change a new iPhone one week ago and previously last few years I am able to switch my bkb account over to any new iPhone via sms OTP. However it is not successful this time round and I believe it could be due to the purging of foreigner account without a legit visa. When I try to do what I did before , it say I must go to the bank to authenticate my account. I can access my account via web browser and do transfer to other account, of course it’s not as convenient as using the app on phone.

I am hoping to get advice here if I should try to go to the bank to get it install on my new iPhone and risk getting my account closed at the same time ? Or I should just leave it and use only the browser version ? Thanks so much
