On the iPad Pro 12.9-inch (3rd generation) cellular model, when you touch the screen with four fingers and then move your fingers, the touch is no longer detected. The same operation with one to three fingers works normally. This phenomenon does not occur when accessibility is turned on. Is this a beta-specific issue that will be fixed in the official release?

We have confirmed this issue also occurs in iOS 26.3.1. In the app we are developing, this bug significantly impairs the app's main functionality, so we would like you to fix it as soon as possible.
