@AlexHerman1 Thanks! Do we have this error appearing to different users or different devices?

[AlexHerman1]

@tommasini we have 8 total tickets on this, seems to appear in a variety of different scenarios. multiple people reported from log in screen, two seem to have it upon trying to use biometrics. i am sure they are not all on same device, it looks like mainly an android issue.

I ran into this issue on an app that I'm creating. For me the issue was due to the fact that I set the storage type to Keychain.STORAGE_TYPE.AES and saved password using Keychain.setGenericPassword(...), then later in the application it changes the storage type to Keychain.STORAGE_TYPE.RSA and calls the same setGenericPassword method but with the storage type being RSA instead of AES. To fix this you need to call Keychain.resetGenericPassword(...) before you call Keychain.setGenericPassword(...) the second time

I've encountered this same error while clicking on Import a token. After dismissing the error I could see how the Import a token link was then greyed out (not clickable) and no other function responded / MM stayed frozen.

I solved this by re-starting the app (closing and opening again).
