Problem: the Play Store is not fetching the current test build v1.53. As a result, the test build is not being distributed, and only the production build v1.45 is available for the specified devices (the test build v1.51 was previously available for these devices).

Notes:
- regardless of the specific app, it is normal for the release of the internal test version to sometimes be delayed by up to 24 hours; this issue can usually be resolved by taking certain steps (see below)
- I tried the following actions to force the Play Store to fetch the current build but none of these actions worked:
– cleaned the Play Store app cache of test devices
– cleaned the Gmail app cache of test devices
– logged out of the test accounts and logged in with my main account and then switched back to the test accounts
– deleted the test accounts from the developer console and then logged them back in after a while
- please do not confuse this issue with  FS#4309  (here, no app is delivered by showing an error message)

1. start game
2. play through till end > end screen is shwon up
3. check buttons

BUG: a white plane is overlaying the buttons. As a result, the strings are not visible in this state (it's briefly visible in moment of tapping)

Note: it's fine for SM-G991B-android13, SM-T733-android14, , SM-A156B-android15

1.51

Problem: the app is not available for the mentioned device type due to error 'This app isn't available for your device because it was made for an older version of android'

Notes:

- we already had this issue some time ago » http://www.flyspray.foxandsheep.com/index.php?do=details&task_id=4187

Situation: I install and launch the app and the permission prompt 'access photos, medias and files' appears. I deny this permission and the splash screen appears

Problem: the app stuck in a blue screen after the splash screen → SC31

Note: it occurs only for this android version (6.0.1), all others (6.0, 7.0, 7.1.1, 8.0) are working well for this situation

Situation: games - game #02 (Peter Polaris): I finish the game

Problem: the forward button is not highlighted when the game has been finished → SC06

Problem: I noticed following graphic issues:

home screen
- title/banner (outlines) → SC07

inhabitants
- start button (outline) → SC08

loading screen:
- edge of white area → SC09

ingame
- highlighted forward button → SC10

pause menu:
- home button (outline) → SC11

Problem: the volume of the background music and the sound effects have changed. As a result they drown out the voice over. It's very noticeable in the first scenes (breakfast at home, kids in garden)

Situation: I enter the home screen more than 5 times (over 10 times in all)

Problem: the rating popup doesn't appear

Situation: the device language is one of the non-EN languages (ES, FR, IT, DE, PT). I install and launch the app

Problem: all device languages that are non-EN are not taken over. As a result the app is using language EN as default.

Note: this bug occurs only for iOS11 and iOS12, it works properly for iOS8, iOS9 and iOS10
