  1. Font size will not change within apps like eBay, Google Maps, the Telegraph and many more that not support these feature.
    Just bear in mind before you switch to iPhone,i did that and was not able to properly read without strain as letters where very small.
    I contacted apple support and they confirmed that this is app developers issue.
    For me that was a deal breaker and i returned to android and send the iPhone 11 back.

  2. I think you decided in haste, especially if just font size was the issue. For one, the font size is system-wide, and most apps follow it. I specially tested Google Maps and observed the fonts changing. In fact, with iOS 15, you can increase fonts for particular apps; if you need to test it, the steps are in the blog itself.
