Not that I know of with current releases being minor version updates, once they push an iOS 14 beta then there should be some bigger updates. I originally set it up to get iOS 13 beta to get the early features of a major release. These minor releases don't usually have fun new functionality, I've just left it setup. I've not seen any issues with beta though, as with any "public beta" it's a pretty generally stable build before they push it out. I'm sure it's mostly a sanity check for them to get a broader user base and catch any minor misses - always a chance of some big issue though I suppose. Not that it's unheard of for a final public release either.Anything fun I'm missing with not having the beta setup currently?
