FxRphoto, can you please help in understanding how come NIK works perfectly for you? What operating system are you using?
Is there anything else you have done to get it to work? How come you don't seem to have the "updating fonts" message that so many of us have and that makes Affinity crash?
As for NIK 2018 and NIK 2 here is what DXO support had told me: "I do apologize, but as Affinity is not a certified host software, we cannot provide support for that combination.  This does include Nik Collection 2 as well." 
So what is the reason Nik2 will work better than Nik2018 according to your findings?
thx

to add to Steven's comments (and the many other that have been posted around this issue)
I make much use of the combination mac Photos->Affinity Photo->NIK (now from DXO). With 1.6.7 it worked well.
I contacted DXO and their response was:
"the combination of Nik Collection 2018 and Affinity Photo is not officially supported"
I was curious if the new NIK version (Nik2) would work and DXO responded:
"I do apologize, but as Affinity is not a certified host software, we cannot provide support for that combination.  This does include Nik Collection 2 as well."
 
the question is why Affinity is not been supported by Nik and if perhaps enough Affinity users need to express their needs/requirements to find a work around? (besides using NIK as a stand alone app?)
