dop2000 Thanks a lot, it helped with CBHash!
But now I got into the same thing with 'cranberrygame_CordovaGame' :)
upd.
Well, I also updated the 'rex_date' plugin using the link above and only 'cranberrygame_CordovaGame' and 'cranberrygame_CordovaPowerManagement' are currently causing the preview problem.
However, there is 'MobileMasterIAP', which does not cause this problem, but introduces a number of other bugs that cause the preview screen to simply go black.
