Problem with lyrics

Hello guys, I am from Greece and I want to report a problem. I am a Musixmatch curator (lyrics provider) and I saw that some songs on Apple Music suddenly stopped having lyrics. I talked with the mxm's moderation team and they told me there is no proble. Not only this but there are also problems with more popular songs like Keep on loving you by cigarettes after sex. If you try to open the lyrics will close automatically. Please if any moderator or dev see this give me a chance to explain with proofs and screenshots because it's been 4 months now and some of the most popular songs in Greece suddeny stoped having lyrics (with no Musixmatch problems). It is serious, and please don't ask me if I had updated version or the same stuff. My phone and internet is ok and I am 100% sure that there is a problem
