Hi res and Lossless tracks in apple music

Hi I am facing issue with hi res and lossless tracks . I am using broadband with wifi at 40mbps speed .

most of the time Hi res track dont even stream it and donot play and simply skipping to next track in library

some time lossless track and hi res tracks start to play and stops after exact 15 second

when i download the hi res and lossless in hi res option on with dolby atmos play off and dolby atmos download off both hires and lossless tracks plays properly.

so is that the issue with my broadband wifi connection of 40 mbps per second ?

I am on latest version of 17 ios with Iphone 14 pro

Regards

thank you in advance
