Sry this is not a bug report but a recommendation.
We are following magento development from releasing on - and struggle hard with all the bugs.
What i realize is that lots of bugs are reported back meaning the magento team answers like "what version of xyz do you use" or "we cannot replicate this issue here" etc.
This is very time consuming for us users and also for the magento team i guess so i would really strongly recommend magento to set up demo stores ov each version and each upgrade so we users can test the bugs on official installed versions.
Also a recommendation for the server systems (Ubuntu/Debian), PHP, Nginx etc.) would be great so we users can use the same stable systems for our clients.
Me and my company are a bit tired of all the major bugs at the moment with magento 2 because some bugs seem to here for over half a year and are still there. Pls magento take this not as an attack but just a try to speed up bug fixing as a bug reported on your systems need no further pingpong in a bug ticket regarding versions, installed os etc. etc.
