This issue here with my gate has been getting worse and worse over a couple of years and I think if I dont fix it the the lock bolt wont even reach the latch eventually
You can see up the top how large the gap is vs the bottom of the gate
I had a look and the fence post where the hinges are screwed onto is twisting counter clockwise from the top. ( had to tell from photos but its definingly twisted)
The bottom of the fence post is concreted in and is concreted around to so its pretty square but the top is warped
