Hello @Manxe, I would recommend updating the application to the latest version, dark mode on your device shouldn't affect the colours in the application anymore. In case the issue persists, please, let me know what version of Android, device and Windy (can be found at the bottom of the Menu) you have.
Would you describe the bugs you are experiencing closer?
What do you mean by 'high wind animation'? If you are referring to an altitude in which you are viewing the layer 'Wind' – this can't be customized right now and it is not a bug but a default setting.
The Startup location is customizable. In order for the application to remember and later display your settings, you have to be logged in with your account.
Also note, that the 'Use GPS' option requires application's allowed access to your device's location.
In case your preferred Startup location isn't correct even if your settings is right, please, let me know what version of Android, device and Windy (can be found at the bottom of the Menu) you have.
We are not ignoring new features requests but we can't comply with all of them. Thank you for understanding.
