Not a native English speaker here, so forgive any spelling mistakes. I have an Iphone 5S stuck on the IOS 12.5.5, I just found out about the Beta Software Program and installed an IOS 15 Beta profile on my device, but whenever I try to update my software, it states IOS 12.5.5 Your software is up to date and a new update never shows up. I've restarted my Iphone, but the update is still not available. Most apps require IOS 13 for me to download or update my apps, so I need an IOS update!!
