Uploading your images to the cloud is the same process as exporting your images and videos from the GemLightbox app. You can find out how to export your files here.
Please ensure that you have downloaded and signed into your cloud applications prior to exporting your images and videos.
For Apple devices, if you are unable to find the Cloud service in the list of apps, scroll to the end to find More and ensure the Cloud Service is toggled on. Once toggled, the app will appear.
