I too, noticed the same issue. And I just noticed it clearly this morning. With that issue also, it is difficult to find your opened up Spotify app on the taskbar. until you realize that it morphed into a blue Chrome icon. Glad it has been reproduced, as when opened up, it displays a blue chrome icon, but when closed, it reverts back to the original green icon, as it should. Before I looked this up, I told myself, no way, not acceptable. It is like telling us to eat blue chicken, lol. T'aint 'appening. Looking forward to this fix.
