There may be a manifest file which supersedes ours.
If you see this error message than you will need to merge your GCM sender ID into your existing manifest file.
In some rare cases, you already have a manifest.json file on your website that conflicts with the aimtell-manifest.json file. If this is the case, simply copy over the "gcm_sender_id" field from our manifest to yours.
For instance, let's say your existing manifest.json file looks like this:
"name": "Awesome Website"
Then you would update it to look like this:
"name": "Awesome Website",
Please note, if you have a manifest file which supersedes ours, then you will need to manually update your GCM Sender ID if you add custom GCM/FCM keys within the dashboard.
