Where do I get support for Affinity Software?

Serif Software
Affinity Designer and Affinity Photo are supported through the Affinity Website
 
The best place for asking software questions, reporting bugs and requesting features is on our Affinity forum – it is where we all hang out. If you haven't already done so make an account to post on those forums (this is an independent login and not the same as a serif.com or affinity store account).
