Beta 3 of DaVinci Resolve 14 has been released and for me it is working better than previous betas, although is not perfect. For example, when I nested a sequence in another sequence, I could no longer hear sound. However, I can now playback audio in the new fairlight audio page. As it is still beta I would not 100% trust it for real work but it is getting there.
