No. It affects only the Synology applications.
@mpalermo73’s info is out of date.
PMS 1.41.0.8994 is available for systems running DSM 7.2.2. Download the APK from plex.tv: https://www.plex.tv/media-server-downloads/?cat=nas&plat=synology-dsm72#plex-media-server
Due to Synology changes, there is a separate PMS package for NAS running 7.2.2.
If the NAS is already on a prior DSM 7 version, updating is straightforward:
- Uninstall Plex Media Server. When prompted, choose the “Uninstall Only” (first) option.
- Update DSM
- Reboot the NAS (update probably does this anyway)
- Download and install the 7.2.2 package from plex.tv.
If the NAS is running DSM 6, there are more steps involved Read FAQ 27 carefully before migrating from DSM 6 to DSM 7: FAQ 27 - Migrating an existing PMS from DSM 6 to DSM 7.
