@playpixel I have nothing against the BETA version, I recommend it here in the forum for many people, and most of the people who tested it had their issues solved.
I use the latest stable version (18.07.13) because I have a "normal" Rpi3 (it's not Rpi3 +), and everything is working fine, it's not worth it for me to switch to the BETA version, since I have no problem.
If it is to recommend a version for you to install, I recommend that you use the BETA version (but never update it!), If you did not like BETA, use the latest stable version 18.07.13.
