Button not working and Shelly app asking for user and password

Hello,

Since I updated the shelly app and the dimmer 2 firm the app is asking for user and password.

I can’t control the lights through the button or the app but I can still control through Alexa.

I asked to Shelly support about it but they say try with 0000 or 1234 and both are not working.

Can sbdy help? Has sbdy found something similar??

Thanks!!
