Yes, I have had to create my artboards using the "insert artboard" button rather than command dragging them like I usually do..... I had lost access to a few hours of work because of this, but I ended up transferring over all of the files to artboards that were able to export.
I no longer have the file, but this issue is easily evident..... COMMAND DRAG AN ARTBOARD AND TRY TO EXPORT IT. Daniel and I are having the same issues.
Some issues I seem to have that he doesnt is that sometimes I find elements in large documents with lots of layers that are un-deletable. That has only happened a few times though and I end up just deleting the artboard alltogether.
This update for Affinity is actually quite buggy.... I have had other issues of dragging and dropping two or more pdfs into designer and having it freeze..... almost every time I try to drag two or more.
Affinity Designer also crashes more than any other program I have..... sometimes it will freeze up multiple times while working with documents that have a lot of artboards..... it actually crashes the most when I move artboards around and the OBJECT SNAP TRACKING seems to overload it or something.
Hope this gives some insights as to what can be fixed. I absolutely love Affinity.... and if these issues were fixed, I could use it with clients and not feel embarassed.
