Sorry to baffle you. 
My intention wasn’t to label a certain release as good or bad. In fact I even did appreciate the current release in parts. So it’s not that.
I hoped to have emphasized that the ‘specific issue’ is the lack of focus on quality of (user-)experience for some time now. At least in my humble opinion.
I owned a jolla 1 device back in the day, even had a Nokia N900 with maemo before. There was a time, when basic operations (phone calls, data connectivity) simply have been working. This is no longer the case with recent updates, unfortunately. For some time now, I’m reading early access comments, wait for public release and then expect the worst and hope for the best. Results are… well… at least mediocre.
