Have you tried removing the gray plug on the top of your hydraulics and reinsert? It has a plastic clip on the top you have to pull and then it releases the plug. I have a 2021 40IH and had to do this last week, neither of our two large hydraulic slides would move. The jacks would not move either, tried to manually lift the coach and jack didn’t move. So we new it was hydraulic related. Removing the gray plug and then pushing it back in seemed to reset or sync back up. Slides came in and jacks stored when I hit auto store.
