@DTS Engineer I appreciate if you can comment on that as well. Thanks,

In this case that means setting the allowUltraConstrainedPaths property and then, once you’re connection, looking at the current path to determine whether it’s ultra-constrained. Thanks for the advice! Then, is it a fair understanding that if my app is implemented accordingly, the app will be considered as a carrier-constrained.app-optimized app? Also, is there a way to test(simulate) a ultra-constrained network on a device or a simulator? Thanks again!
