[bug] /activities endpoint not reporting when offline transcoding is happening

Server Version#: 1.43.3.10828 (Windows 11)
Player Version#: 2026.13.0 (1835) (iOS, iPhone 14,2)

Issue:

I’ve written a small script which checks to see if Plex is currently in use, by querying the /status/sessions and /activities endpoints.

Following a recent PMS update, the /activities endpoint has stopped reporting the media.offline.transcode phase of a download request.

It remains empty during transcoding and only populates once the file begins the actual downloading/transfer phase.

Actual behavior:

<?xml version="1.0" encoding="UTF-8"?>
<MediaContainer size="0"></MediaContainer>

Expected behavior:

<?xml version="1.0" encoding="UTF-8"?>
<MediaContainer size="1">
  <!-- Entry detailing type="media.offline.transcode" -->
</MediaContainer>

Can confirm defect also occurs on 1.43.3.10861 (Windows 11).
