After Synology breaks video station, plex, HEIC, H.265, backups, update now also breaks Surveillence station. What is going on there?!

Installed DSM 7.2.2-72806 on my DS1821+. The update automatically updated Surveillance Station to 9.2.1-11374.

When updating I received the following notice:

Surveillance Station will automatically install the Surveillance Video Extension package. After this update, the Live View Analytics app will no longer be supported. The support for HEVC (H.265) cameras will undergo the following changes, while AVC (H.264) cameras will remain unaffected:
Unsupported features:

Motion detection by Surveillance Station

Continuing to take snapshots after events for email notifications

Adjusted mechanisms:

Event snapshot

Thumbnails (e.g., thumbnails for IP cameras, detection results, timeline preview)

There was also a warning stating:

DS cam Android 3.10.0 or above, iOS 5.9.0 or above:

H.265 camera streams might not be able to play:

If any issues occur with live streaming or video playback, consider changing the camera’s video format to H.264 or using a mobile device that supports H.265 format.

Once the update was finished and I opened Surveillance Station I received this warning:

Some H.265 cameras’s motion detection has been reconfigured or disabled. In this update, Surveillance Station no longer supports H.265 cameras to configure motion detection using Surveillance Station ‘s algorithms. The motion detection setting is automatically switched to using camera’s built-in algorithm if available. Otherwise, the motion detection is disabled. The related functions (e.g., recording schedule, notification, alarm, and action rule) will also be affected.

Testing Surveillance Station in Chrome it is completely broken. There are no previews for my cameras, recordings can’t be played back, etc. This all worked before the update, although I normally use the client. https://imgur.com/a/47m5ukO

Using the Surveillance Station Client on my Mac, there are almost no changes. The camera previews work, hovering over the timeline in monitor center displays a preview, recordings can be played back, smart time-lapse recording in h265 works, etc. https://imgur.com/a/RBVM2ET

Under the camera settings, I can still set a recording schedule, the only thing that was removed is the option to use the Synology detection algorithm under Event Detection. Advanced Event (Smart Event) settings still work. https://imgur.com/a/TFoKvJk

In Monitor Center all previous events from before the update are missing (I can’t jump to the last motion event), but the files themselves are still there in recordings. https://imgur.com/a/PJHBVd3

The iOS app still works fine with no issues.

Ultimately the only change for me is that I now have to configure event detection by logging into each camera recording in h265, everything else is the same as before.

Cameras I tested with are Hikvision DS-2CD2385G1-I recording in h265+ and Reolink E1 Pros.
