Many would tell me that beta is a test and things can happen. What they don't know is if things are not fully made available to be tested wholly, then a final grade cannot be determined with just limited availability or full feedback be given (I like to take my time in testing/playing fully, not to be rushed). With that, I give this event a solid D+ and would hope they (Inno) would improve if they want me to spend on either world.
I might be wrong on this, but I believe the mobile version of the game has to go through some sort of approval process before updates are made available for it. This may be why mobile tends to lag behind PC, since it's not entirely under Inno's control. They could flip it the other way around and simply delay the PC update until mobile gets approved, but I think it's clear that their timetable operates based on the PC version so that's probably not going to be changing.
This kinda goes back to the previous discussion about PC vs. mobile - I think PC is still Inno's primary platform for the time being, with mobile being supplemental to it rather than an alternative. Some players do primarily use mobile (it sounds like you're one of them), but I believe the focus is really on PC when it comes to beta testing and mobile kinda takes a backseat because other than the UI looking different and lacking GvG, the game is otherwise the same. Just some time is needed to observe whether there are any mobile-exclusive bugs.
