I had a hydraulic hose serving the loader bucket spring a leak, decided, since all the hoses were the same age, to go ahead and replace all of the hoses that attach to the hard lines. All replaced, bucket operates fine, loader will lift, but will not descend by joystick control. I have it back down after shutting down the motor and opening/loosening the connections on the forward location on each lifting arm hydraulic cylinder. I have a feeling this is related to air in the system, but I am a cautious person and I am looking for any advice and help as to any other possible issue that may be causing this. Any help is appreciated. Thanks

Its not related to air in the system The return path from the base end of the lift cylinder is blocked. Bad coupler or one of the hoses has been miss- routed.

I thought the same thing and reversed the hoses, that just reversed the joystick control. had to push forward to lift rather than pull back. So, if I understand you correctly, if I take the line loose at the hard line connection down by the frame, and loosen the connection on the base end of the lift cylinder, to "take my finger off the straw", if fluid does not flow out it will indicate a blocked line. Correct?
Not exactly. I don't know the specifics of the plumbing on that loader but if everything else works take the power beyond hose off AT THE TRACTOR and stick it in the hydraulic filler. Start the tractor and try to raise and lower the loader. The flow coming out of the power beyond hose should not stop.

Turning the steering wheel back and forth is a way of clearing air. Your symptoms don’t sound like air.
Replaced all loader hoses on B20 with no issues. Only had to replace one damaged hose on B26.
