Hi please can you help me. I got Affinity for my iPad Pro 2018. Many of the functions simply don’t work, from the erase brush to other tools! Why is this happening? Am I doing something wrong? I also have this on my iMac and have similar issues. Affinity isn’t as intuitive perhaps as I thought. It’s actually reducing my confidence. I got Affinity to rekindle my love for creating and photography. Is there a way that I can re install this on both my iMac and iPad?
