@jonah9000 We have received reports across multiple aircraft (from multiple developers) of autopilot issues following some changes that were made to the default Working Title GNS530 in MSFS SIm Update 14. We are hopeful that some changes that are due to be released with MSFS Sim Update 15 should improve this.
In the meantime, if you could kindly contact Just Flight support, they may be able to assist with some short-term troubleshooting steps: https://www.justflight.com/support
