Update to this, still no sign of Generation 2, but one thing which has appeared on my game was a shocking message about
Failed to initialize
Hardware no longer compatible, sorry!
Was fairly sad about it, but said for the lack of any information about new devices being removed from compatibility lists I would go for a reinstall.
Works fine now again, was back in game, using the mass transfer tool but still though, fairly scary random bug, last update had the game create a clone icon which did nothing on my phone, this time it threatened to just not run anymore on the thing.
Gotta lovvvvvvvvvvvveeee Niantic.
Edit - New patch has also bought with it a captcha system for people who are "drifting" their eggs to hatch. Basically if you are in an area with poor GPS and you leave your phone on a table or so with Pokemon go Open it would walk about randomly and slowly hatch your eggs over time, Niantic have come up with a way to detect this sort of movement in a small area and now fire a captcha every minute or two to halt anyone trying to hatch those eggs without handing over €1.50 for incubators. Can't be having that!
In other news Pokemon Go is now listed as Number 75 in "top apps" and has fallen to 7th in the "top grossing" category. Now does seem like a good time for Niantic to do something or at least acknowledge the games fall from glory... perhaps it could be time to roll out another increase to the phone hardware required, that way Niantic could suggest that the fall in user numbers was due to hardware compatiblity dropping.
