@androidshivam Was there a previously authenticated user on this device, and the refresh token expired?

I've tested on multiple devices.I'm facing this issue on first install as well

[abdallahshaban557]

@androidshivam are you still facing this issue?

[dnys1]

@androidshivam - is the confusion that fetchAuthSession is throwing an exception instead of returning a value of isSignedIn = false? Can you add a try/catch block and handle a SessionExpiredException the same way you'd handle a value of false for isSignedIn?

[abdallahshaban557]

@androidshivam - did you try the workaround provided by @dnys1 ?

[Jordan-Nelson]

@androidshivam - If you are still facing this issue after trying the solution above, please let us know. Otherwise we will close it out. Thanks.
