Using Apple Pencil will shut down RD client when connecting to the remote computer. This situation happens after updating the app today.
Similar situation with iPad users in our company using the Zagg Pro Stylus on iPad (9th generation) with IOS 16.1 and also on iPad Air (3rd generation) on IOS 15.7. For the iPad Air the RDP sessions worked fine until the last RDP update to 10.4.4 and then it was noted on 10/12/2022 that it dropped the RDP connection whenever the pen touched any shortcut or menu item on the RDP connected desktop. For one user with a iPad (9th generation), this only started happening yesterday on 11/10/2022. The stylus on all of our iPads still works well with all other apps.
