Apple Music keeps removing downloads on my iPhone

There’s a new bug in Apple Music that doesn’t depend on the phone settings, available storage or anything else. Downloaded music disappears randomly so I have to download it again, moreover if I download it in lossless the downloads disappear IMMEDIATELY after downloading is over. This is ridiculous considering the size of music files. The same bug is present in Apple Books, but with books it’s more manageable since the size is way lower. Any idea on how to fix this issue without switching to another streaming platform?
