Not yet fix?

I understand all of the above but why screw up something that was working perfectly fine before?

I would rather pay for Jellyfin and have more people working on certains issues.

Sometimes adding new additions or improvements to a product introduces unforseen consequences. In this case, a regression was introduced. Unless you can find evidence it was done on purpose, those issues were introduced unintentionally despite previously working.

Most likely it's not as easy switching back the code that pertains to the player as there could be new things that depend on it.

All the previous releases of the Roku app are available on the Jellyfin github. You have the power to switch back to older versions of the software if those worked better for you.
