POWR Lookbook Gallery

We have downloaded the image slider app by POWr and we are very disappointed with the performance. We have attempted to upload images and it will just stay stuck on loading forever. We have one image that has currently been stuck in loading for over an hour. We would love to use this app but the functionality doesnt seem to be there and when we have attempted to contact support, we havent received any reply at all. Will be deleting this app
