New Features & Changes
- Mouse support has been improved with scroll gestures, new button associations (hold and drag), and hot corners.
Remaining Issues
- Enabling/disabling Cellular data while on home screen still shows incorrect status in Settings.
- When a bluetooth mouse is connected, dragging apps from the home screen into split-screen multitasking becomes impossible (since 13.0, used to work fine in early 13.0 betas). work-around: disable assistive touch, turn off the bluetooth mouse, and reboot the iPad. id: FB7460912
- Mail Sync issues with push notifications, but mail needing to be pulled when opening mail app - Since iOS13 Dev Beta 1
- Security Contents
- When using a bluetooth mouse under iPadOS:
- cursor occasionally moves to the center of the screen by itself. After it happens once, it will keep happening every few seconds. Workaround: turn off the mouse and turn it on again → This seems to have been solved around beta 4. The cursor occasionally still gets moved to the center of the screen, but it now happens rarely. More importantly, when it happens, it does not keep happening, so the workaround is not needed anymore.
- cursor stutters, occasionally a lot, even with powerful devices such as the 2018 iPad Pro. → seems to have been solved around beta 4.
