I looked through the logging and this seems to be the first error related to installing the app. I can't figure out what is causing it, but maybe someone else can? default 13:02:13.325727-0700 installcoordination_proxy -[IXAppInstallCoordinator setPlaceholderDisposition:error:]_block_invoke: Failed to set placeholder disposition to Delete Placeholder on <IXInitiatingAppInstallCoordinator<0x896806bf0> identity:[[REDACTED][REDACTED]] uuid:[REDACTED] creator:InstallCoordination Proxy> : Error Domain=IXErrorDomain Code=25 "Client installcoordination_proxy (pid 470) is missing entitlement to set placeholder disposition."

The response here seems to imply it is possible to pick up the middle mouse button with UIEventButtonMaskForButtonNumber(), but after trying 3,5,4,6, etc. I am never seeing my gestureRecognizer being called. Specifically I am using: oneFingerTapRecognizer.buttonMaskRequired = UIEvent.ButtonMask.button(3) Can someone clarify if detecting the middle mouse button (on a bluetooth) is really possible?

After looking at this again, I realized that the price of the plan is (mistakenly) $19.99, so the price being shown is not the difference, but the price itself. However, this is not the price I have configured in Apple developer portal for that subscription tier. Is there anywhere special I have to configure Sandbox prices (I am not using a .storekit file).
