Changing phone number in jupiter

I was really enjoying Jupiter for almost a year now and now my friend suddenly lost access to their account because she lost access to her phone number and there is no way to change their number without having their old number like how is that even good that too for a Neo bank and when I researched about it you guys said u would role out an update where you can change the number in April 2022 now it’s Jan 2024 still u guys haven’t updated this. I have been sharing Jupiter with my friends and I recommended this to them and now this happened to them really don’t know what to do, one word terrible
