Missing streams

My listens are not correctly counted for a lot of songs and for some songs listens before a certain date were lost completely.

For example my listened to album has very few listens for the individual songs.

In general it also shows a “first listened to” date that is years after the first listen.

This has not always been an issue, as everything has been correctly shown up until maybe a year ago? So listens that were previously counted, and shown are no longer displayed/counted.
