Syncing issues

sometimes when I’m playing a song on Spotify and I come here to look at my stats it doesn’t sync properly . For example on my recently played songs that I know I listened too won’t show up. But the. I’ll go on Spotify and look at my recently played and they’ll appear there so it’s an issue on the stats.fm part and it’s just not registering. And like also for example from certain songs of the the top of my head “relevant” by lil Uzi vert it’ll say I have less minutes or I have listened to it for less time than I actually have.
