First, make sure you've got the latest app version.
1. Download the latest app here:
Due to store restrictions for the types of features we add, we're not able to update the same app every time. So sometimes you need to download a new app and re-register.
2. Make a Backup
If you are using an old version or a trial version, export your data in JSON format before you install or update your app.
3. Have You Already Registered The Web App?
If so, use the QR code solution in step 3a. If not, skip to step 3b.
3a. Yes, I have registered the Web app: Use the QR Code.
Open the web app and open a Campaign Log.
Click on the cog icon in the top right corner.
Choose the Edit License Key option.
Choose the Show License Key QR Code option.
Open the mobile app on your device.
Scan the QR code.
You should now be successfully registered.
3b. I have not registered the Web app: Paste your email and license into a test plain text file.
Note that spaces and invisible characters from a careless copy & paste operation will result in a registration error. To avoid that, paste your email and license key into Notepad or some other plain text editor.
Check that there are no spaces before or after the email address and the license code.
Also ensure that the license contains all the == signs at the end. Those are part of the license code.
4. Open the app and register
Now open the app and register, copying and pasting the text from a plain text file to prevent spaces and invisible characters.
