If it's really cold where you are at, run the furnace for a while to put heat into the underbelly on those hydraulic lines. Try it again on a warm day with sunshine on the jacks or use a hair dryer to warm them up a bit. Same for the hydraulic reservoir and pump.
Check to see if you have the upgrade for an 80A circuit breaker on the hydraulic system. There was a TSB put out about that. Yours being 2020 it should have the 80A breaker.
The other thing is some people have found even with the 80A breaker they wired it wrong from the factory and the hydraulic system is going through the 50A breaker.
