For me its working fine, the previous version was build on vulcan, meaning it was stuck in a old android version that barely any device could still use, the new version allows a much wider ranger of devices to play the game ( even if your device isn't 'supported' via the google play store you can still download the apk and install it manually) so yhea making a new version with new mechanics isn't an upgrade its a whole new game. yes they have expirience tough it will take some time, dont forget old ark was running for some time so they had alot of time while the game was live to do improvements. the game is only live for a few days.
