@Sir_Robert we don't know why (but we can guess). The custom mp3 support was being removed for quite a while. All the new devices (Sense, Sense 2, Versa 3, Versa 4 (not sure about Versa 2)) lost that feature. It means, for over 2 years no device was released allowing users store own mp3 files. Ionic has been recalled and I believe, the only device which still supports it is old (and discontinued) Versa. Yet last year, the support for uploading MP3 files has been discontinued, too (the PC software) so even Versa owners are unable now to upload music onto the watch. So it isn't something new, we could see the direction Fitbit took for quite a while and expecting the music storage to be back is like waiting for piga to fly. The surprising decision of 2022 was removing a music support on recent models entirely (no Deezer or Pandora, no music controls, etc.). That only tells us that with next models to come, we should rather expect less than more in that matter. If you need a watch capable of storing user's music then you need to look somewhere else.
