Hi, I can't change the version from my app... Xcode give me a error, when I try to change the version for older devices (under iOS13). I get error messages inside the codes there tell me, I can't use this code on older versions. Maybe somebody know how to fix it? The Apple Support can't/want help and say I need to ask here.We have a restaurant app and we don't want it only for iOS 13 and up, because a lot of customer have maybe older devices like iPhone 6.I use a WebView code/setting. So nothing special but yes... like xcode not availabel.Screenshots:https://ibb.co/w4prQnjhttps://ibb.co/LvCtPwJhttps://ibb.co/C8FsrdXhttps://ibb.co/nrRVyZj
