I’m running 12.0.1 on iOS with 6.4.1.0113 on one device and 6.5.1.119 on the other. Things seem to be working very good. iOS 12 seems much faster than iOS 11 and restores the previously expected battery life that went away with 11. iOS12 is not a major release for Apple, but it certainly does improve things under the hood. Response timeon almost all apps, including Logos Bible, is much faster..
Haven’t encountered any issues with Logos at all except for one item that was previously a problem and has now returned. Highlights blink on and off intermittently. Problem seems more pronounced this time than when it was previously an issue. Does it a good bit more often for me, and turning off scrolling view doesn’t seem to help at all this time.
Will keep you posted on any development.
