Of course this is caused byt the engine larger diameter and short landing gear.
Worthy of note, the 320 Neo has no issues, though its engine have a larger diameter yet.
The 302 Neo constantly adjusts the stabilizer trim because it operates in MCAS 100% of the time, they just don't call it MCAS. It hasn't had any problems because it is not being sold to airlines which need to directly transfer 737 NG pilots to new seats. As a result they don't have the 737 cockpit automation, for good or bad, and don't fit into the ground-handling system the 737 does.
