There should be none, but as we are in a testing phase with many of these releases, there may be a localization issue but we can help fix that.
All releases should work within the UK. Could you message me some of the issues you are having with the releases in the UK?
We do have it set up at the moment as an Open Beta on Google, but that is due to how difficult it can be getting players set up with a Closed Beta. We also do use the form, just so we can follow up with a little survey to get some feedback - as we really want to try and improve our releases as much as we can.
All of our releases should work for you within the UK, please could you PM me the error you are receiving, or if it just saying that this release is not available for you?
We are currently updating out website and Beta Test form to remove the option for Google but we are currently working to get this live onto the Google platform ASAP!
