I am having the same problem with importing styles in designer for iPad. I recently factory reset my iPad due to storage issues and was able to download all types of styles before. Before I did the factory reset I exported all of them to iCloud and drive and Dropbox just to be on the safe side. After the reset I downloaded designer and now the files are greyed out. Please help!! I’ve made tons of styles I need!! I don’t understand how I could import them before and not now??? Really thinking about doing another factory reset and letting it download the backup I created and see if that will fix it. Any help is greatly appreciated thank you in advance!!
