Summary
Pushing changes in launched UEFN session causes Cinematic Sequence Device not to show changes while seemingly still playing a sequence.
This behavior I get while using CS device to change material parameters from Parameters Collection.
Everything will work at first and after pushing changes and playing sequence, parameters just wont change, even though sequence will be played (I used audio track to test it). After a couple of pushes hud message device with material that uses MPC in sequence wont show up at all (I was changing text block message to test it), so maybe its even a bigger problem than just a Cinematic Sequence Device bug.
Changes that you are pushing can be as simple as adding print in your verse - it still will break everything.
It started to behave like that after the last update (36.10) and starting Private Session seems to work as normal

Steps to Reproduce
- Create simple material with material parameter (using Material Parameter Collection) that will change anything visually recognizable
- Create a sequence that will change material parameter and add some audio track (to easily check if sequence is playing)
- Create a widget for hud message device with your material and text block. Create a view binding to change text in a text block
- Create a verse device that will set text in hud message device and play sequence. Hook it up to any event/device that you want
- Place all devices and launch a session
- Make some simple verse or scene changes and press “Push (Verse) Changes”
- Repeat Step 6 couple of times
Expected Result
Everything must work the same as in the first launch of the session
Observed Result
Devices wont show changes even though everything is working
