We recenttly bought an S5 Pro Bundel and we are facing seriuos problems.
I am in a city that the humidity usually reaches 85% on the summer ( south Brazil ).
The printer is installed in a room with air conditioning ( 65% humidity in the room)
The Material station (MS) is never turned off, and I only use original Ultimaker materials.
I only open the MS when some spool finish, and is very quickly.
My PVA, Nylon, TPU printing are horrible, I need to keep dry in an external device and keep on MS when printing.
I'm dealing with my local supplier since 1
