Came here not to report having the same issue but to say I am not having this issue at all with my Cessna 172. Cargo company variant. Just spent a ton on landing gear, electrics, hydraulics etc and screen went green again.
But I do have to say, I just bought new landing gear only a few flights ago, like 4 I think. Pretty heavy price to pay to get new gear that often.
OOPS SPOKE TOO SOON. Going back into it and the screen is orange. Tried clicking on and paying for DELEGATED MAINTENANCE and just wasted 20K cos it didn’t fix it either.
The whole system of maintenance needs a redesign. It is unintuitive, confusing, doesn’t make sense and totally borked.
