If you're looking to pair your device to run visual editor experiments or upload new code variables in a new build, having all options available to you, which includes Advanced Pairing is very handy. If you don't have it enabled (you can check in Device Settings and then clicking on Email me or Text me options), you can check out our Advanced pairing docs for iOS and Android.
During your QA process, if you have a previous build of your app installed where you were able to pair your device (seeing the blue, green and red borders only available on dev or paired devices) and you plan to delete and reinstall the latest build of your app to QA, make sure that you log out of your account if you’re logged into an account in your device.
Once you're done that, if you’re getting the latest build, ensure (talk to your developer) that you’re getting a dev build provisioned for your device through Test Flight, Hockey App, Crashlytics etc.
Once you've confirmed that you have the right build that's provisioned as a dev build, load your app, and navigate to 2 or 3 screens and then force close your app.
Load your app again and then go to Settings and then Device Settings to find the device you have on hand. It should be present in the list of devices that have not been paired and recently had a session in the last few minutes or so.
If you can't find your device in Device Settings - go to User Insights and look for your device through a combination of filters, such as City, iOS device, appBuild, appVersion, etc to be able to narrow down your device.
Once you've found it, you'll want to look in the left-hand panel and click on more to be able to expand to see more information about your device and see whether or not the build is "Dev" or not.
Once you've confirmed that you have a dev build in your hands by confirming in user insights or through Device settings, while your app is open, click on Ping Dev Devices in the top right corner of the Device Setting screen.
You should see a pop-up screen asking if you want to pair with Taplytics - click “Yes” where you’ll then be able to create visual editor experiments and upload any new code variables in that new build to Taplytics once your app has been paired!
