I have apps using CMAltimeter to get sensor data, but recently they stop working with iOS 17.4, it is not release but some user running beta version, the is no access to the sensor data anymore (altitude and barometer). Some user report they can fix it by manual the "Motion & Fitness" permission but it only appear on some device. Report has been sent to Apple but I post here to find the solution to fix it.
