Data inaccurate / some tracks stats updating

First, I love stats fm and recognise that having my music data in this way is a massive geeky luxury.

I have a couple of issues:

1. My music stats for 2024 have dipped considerably compared to other years but my habits on Spotify remain the same. I suspect a window of data not updating especially around the time I moved over to StatsFm.

2. I notice more and more that stats for tracks that listen to are not updating. There are tracks I’ve been listening to recently but stats say they they were last listened to some years ago. Other tracks remain on zero even after being on active playlist for weeks.

I’d love for my data to be as accurate as possible. Is this a recognised issue? If so, is it being fixed?

Any help welcome!
