If you're having trouble with the desktop app on Windows, follow these steps to clear your local cache.
This action effectively resets Blink, resolving any issues related to cache conflicts between your local machine and the Blin service. Don't worry, none of your data will be lost, once cleared it will be re-synced when you log back in.
If you have a blank screen when loading blink or are stuck at the logout prompt, clearing your cache will almost certainly resolve this problem.
If you know your way around windows explorer, then simply delete the following folder C:\Users\<username>\AppData\Roaming\Blink but be sure to close the Blink app before running before you do this.
Here are the detailed steps to take:
Shutdown the Blink app on your machine via the Task Bar. This bit is important!
Open File Explorer on your machine
You will be asked to log in again, remember to use your registered email address.
To recap, the folder you need to delete is C:\Users\<username>\AppData\Roaming\Blink but please make sure Blink is fully quit before you do this, otherwise the fix won't work.
