Android: SecureStorage Adding a value after calling RemoveAll() will not persist the value

[phillippschmedt]

Description

When I call Microsoft.Maui.Storage.SecureStorage.Default.RemoveAll() and then add a value, the value will disappear when restarting the app. Adding a value after restart will then again persist it properly.

Steps to Reproduce

Start Android App
Call Microsoft.Maui.Storage.SecureStorage.Default.RemoveAll();
Call: Microsoft.Maui.Storage.SecureStorage.Default.SetAsync(key, value)
Call: Microsoft.Maui.Storage.SecureStorage.Default.GetAsync(key) -> Returns the value
Restart App
Call: Microsoft.Maui.Storage.SecureStorage.Default.GetAsync(key) -> Value is gone
Call: Microsoft.Maui.Storage.SecureStorage.Default.SetAsync(key, value)
Call: Microsoft.Maui.Storage.SecureStorage.Default.GetAsync(key) -> Returns the value
Restart App:
Call: Microsoft.Maui.Storage.SecureStorage.Default.GetAsync(key) -> Returns the value

My conclusion is, that calling RemoveAll() will somehow break the SecureStorage until next app start

@jsuarezruiz I noticed you worked on a SecureStorage issue on Android before. Is there any chance you can have a look into this? Thank you!

@phillippschmedt when restarting the app are you restarting through the debugger or just starting the app back up from the icon?

[phillippschmedt]

@PureWeen It happens in both cases.

@PureWeen I added a repo for easier reproduction.

I haven't been able to reproduce this myself. Is there a particular API level or device you are seeing this on?
