I am new to Affinity Designer and I’ve run into several issues. The tool I prefer to work with is the vector brush tool - but it will only work occasionally. It usually shows a small white circle which changes color depending on where I am working - but no brush tail and no stroke. Occasionally, it will create a stroke, but there seems to be no rhyme nor reason as to why. If I stop on a white space, my line color turns back to white. I’ve watched videos and taken a course, but can’t seem to find a solution. Any help appreciated. I’ve also noticed the program doesn’t always save my latest work.
