Refuses to upload any sketch on iPad 2018 9.7 – Sketch - Draw & Paint Review

The app works incredible and it’s very well optimized for tablet, HOWEVER! Whenever I want to share a sketch it takes an eternity to do so, regardless in what Wi-Fi connection I’m connected. I already restarted it several times and nothing! Is super annoying! Please fix it because it’s getting on my nerves!
