JUrtans channel's video: How to login WhatsApp on new iPhone 15

My mom bought a new iPhone (Iphone 15) and I wanted to help her to transfer all apps etc. Long story short , when I tried to open WhatsApp , I had to log in, where I stuck in screen where I have to put my number. When ever I tried to push button next it brought me to the WhatsApp internet homepage and I could not do anything to log in in a new iPhone and connect the number! I searched google etc., and I found many solutions, but none helped, I even restarted phone and reinstalled application.. Where finally I paid attention that the problem might be in the WhatsApp interface where I remembered that my mom and many other people with sight problems uses bigger text on the iPhone and I figured out I might try to set it back to default, and it worked!! So this fix might not be for most cases where you cant login to whatsapp after new phone, but in some cases where you have put in to the setting Display zoom large text and dont know it affects apps!
