Here is info from another local club. In the past having every device on the exact same version has never been an issue with Practicscore, maybe with this version is is.
Here are a couple of issues we've had as of late. (IDPA) Android Master was a different Version than nooks. Will not sync to master. Work around was to painstakingly create match on a nook and sync to other nooks. These should probably all be synced to matching versions. (USPSA) We had a nook create duplicates of an entire squad. Still trying to figure out how that happened. If you start entering in a score for a shooter and realize that the stage is incorrectly built, you can never get that shooter's stage score to validate even after the stage has been corrected. Work around has been to fix the stage, score shooter, ignore the error, and back out with save. Other shooters that were not scored will validate correctly after the stage modification. Once synced they will validate in the master. Android phone will sometimes show scores when reviewing and other times show blank entrees. At first I thought this was isolated to my phone but after reading ENOS, others are experiencing this as well.
