iPhone font size

Hi there,

I have just switched from Android to iPhone and find the font size on some apps too small. I know you can change the font size through settings and for individual apps through the Control Centre but these workarounds still don't work on some apps (e.g. fantasy football, BBC sport homepage) in the UK. The text remains tiny! Maybe because they are not supported by dynamic type??

It feels ridiculous that this is happening on such an expensive phone. Any ideas or tips please? My Oppo was much more straightforward to change the font size!

Thanks in advance.
