Uh oh. Point taken we have a few pain points with respect to the uploading process. Part of this is due to the Premium features which require us to process the images in a non-conventional straight up way. We're aware and coming up with a more fluid way to deal with processing without negatively affecting the user experience so bear with us on that.
In the mean time, we have set the upload limitations to 10 x 10MB. Hope this is helpful.
Thanks for the explanation. Hope you will fix the issues because the app/community is promising.
