Lightroom Mobile Exporting not working

[Beto350]

I'm trying to export my image on Lightroom Mobile yet it does not work. It shows me a checking message and doesn't go away and I cannot export the image.

Where are you trying to save the photo? Have you given access to Lightroom Mobile to be able to access your camera roll?

Does it help to disable watermark for that image?
If so, please verify what kind of watermark you have set.
If text or image.

Thanks,
Ignacio
