I use the mobile app a lot. I have never been able to get the Mobile Checkin to work, but have never really worried bout it. I just accepted a shop that says Mobile Checkin is mandatory. I've tried everything I know but it still does not work. I was told it would not work with geoVerify so I removed that from my phone and it did not help. The messages I get say that the mobile app was unable to get me location because I have not allowed my GPS to allow it. It say please set the GPS to allow this. I have an iPhone 7 and can not find anything that mentions the GPS, Can anyone tell me how to do this?
Look for a setting that says 'allow Location' under the permissions tab. I have a Galaxy S10, and used to have an S5, and both phones worked great with the Trendsource App AND Geoverify. You have to be in the parking lot before you hit the CheckIn button. Otherwise it wont accept it. Good Luck!
