I have a question that collects GPS coordinates (attached). On older phones it can take quite a while for the data to be collected, so I want to show respondents a GIF image that says 'Checking location...', ideally in the centre of the screen. (I have already created that image). One issue is that a pop-up window appears asking if the respondent allows to be geolocated, so the 'checking location' image would need to appear after the respondent allowed to be geolocated, not before. I would be grateful if someone could tell me how to tweak the existing code to achieve this. Many thanks!
