the pressure is to get things released…start bringing money in…then they worry about fixing bugs…creating trial versions later - often much later. And in the case of bugs, sometimes they forget
If you have an USB eLicenser you can try any Steinberg software during 24 hours (in total). If you haven’t it, wait for the trial version (normally released after first update).
It makes sense to release a trial after the product has been tested in the real world across a greater diversity of systems and a diversity of different ways and then release an update or two - you don’t want new people to be trialing the software when it is buggy.
