shaka player not playing hls on iphone -- 2

You must have skills with HLS , C++, shell, video converting

we are using shaka packager to repackage mp4s to hls - to server from apache webserver to larvael angular website
the hls works on web browsers and android but not on Iphone and ipad
we have got it to work on iphone and ipad but need someone experienced to convert a mp4 into the rightfull audio and video format and then change to hls to get it to work on all platforms.
we beleve that the m3u8 files are being generated incorectly when using the shaka packager and we are having to manualy change the master playlist bitrate ans resolution to get it to work

the issues we have had to manualy change in the playlist are
bitrate for each or the resoultions 1080p 720p 480p 360p we also need 4K adding as well and a conversion to upscale
resolution needs hardcoding in
EXT-X-VERSION:6
