If you can't export your gamma and you're getting an error message, don't panic. There are a few reasons this could be happening.
(1) Your network is unstable.
If your network is unstable or you have weak wifi, that will affect our ability to export your gamma. Try switching to another network, or waiting until your wifi is stronger.
(2) Your gamma is too long
If your gamma is extremely long, then our system likely won't be able to export it successfully. You may need to split your gamma into multiple parts, export them one by one, then merge them together again. We know this is frustrating, and we're working on improving this for future exports.
(3) Your gamma is extremely image heavy
If your gamma is mostly images, or if it contains a few super large images, there's a chance some images won't appear in your exported content. To fix this, you can try taking a screenshot of the image you want to use, then uploading that screenshot. This typically decreases the overall size of the image and makes it easier to export.
