I have an Inspire 1 V2, which I bought used, and have only flown once. The Inspire has been updated to the latest firmware. When in DJI Go, I'm unable to change flight parameters requiring a numerical input, like Return To Home Altitude, Max Flight Altitude, and Max Flight Distance. When clicking on the number field, I get a popup number keypad, but there is no "Done" or "Save" button on the keypad. Once the keypad is displayed it is impossible to dismiss, if I go back to the camera view and then return to the settings, the keypad pops up again. The only way to dismiss it is to restart the DJI Go app. I'm using an iPad 2017, which is on the latest version of iOS 12. I've deleted and reinstalled the DJI Go app, which does not fix the problem. Has anybody experienced this, and how do I fix it?
