No desire to eat after protein shake

Started drinking protein (whey+casein) recently, just as a supplement for my regular nutrition, don't make any goals out of it.

When I take [whey] one after workout I don't want to eat for hours then. To the point I can't even force myself to eat. Obviously it's not okay to skip meal venues. I'm curious if it's temporary and if anyone faced the same problem.

Thanks in advance for your thoughts and advices!
