My Question or Issue

Yesterday I was listening to my liked songs in chronological order.

I realized I had 4k+ songs liked because one time I just liked a bunch of albums on my phone to download them for a flight. 

I went to the albums and removed them from liked.

These were not artists I'd listen to lately so it did not change my current liked songs as I was listening to them while I was doing this.

Now I check this morning, I was gonna listen to my songs and what I find is everything from the past 1.5 years disappeared. These were random songs from all different albums and artists, which I definitely did not remove yesterday.

I am already paying for Youtube Premium so only my liked songs library kept me with spotify but if I can't get them back I am just going to cancel as there's no point in keeping it. 

Is there a feature to roll back a backup or something?

Thanks
