Conversation over electronic media is always challenging.
And I can only repeat it was not clear, that you have no BBFP in front of you as you did not tell this !!
If you would have stated this out clearly, then you would surely have got another answer,
as then its clear that you can not try on your own.
I can only speak abount myself. I have a fulltime job and family.
If I see that a topic comes again and again, then I make some thoughts to make my support more efficient
as I need to housekeep with my priveate time.
Then I write sometimes a blog article and then only refer to it.
Its impossible for me to answer the same things again and again.
And now comes the part where you really should be thankful.
With all other companies I know, you can only deal with the support and the quality is "so so " ...
Here in the RME user forum you get high quality answers from the lead architect of these solutions.
And this in a very narrow response time.
If you put all this together, tbh, I think there is no real reason to complain.
