favourite tracks are different across devices

when i add tracks to my favourites list on my computer (in the browser or on the windows desktop app), they don’t show up in that position on my android phone. the screenshots below are taken at the same time, the playlist, in both cases, is sorted to show recent additions on top. as you can see, the songs by claud and night tapes are missing on my phone even though i’ve added them in between “poligon” and “dirty vibe” on my computer. i have added the songs hours ago. all devices have an internet connection. my favourites list looks the same across browser and desktop app but different on my phone.

i have noticed that this only happens with tracks which had been added to the favourites before but which i removed, then readded. still: the playlists should be in sync across devices. this is very annoying.
