Problem with blink reconfiguration

since last Home Assistant upgrade, my blink integration stopped working.
In the integration panel it says I have to reconfigure it.
Each 20 minutes I receive an sms with a token. When I try to reconfigure I don’t get any sms.
I try to use the last token I received but it didn’t worked.
So I wanted to delete the integration and rebuilt it, but I have only a button to reconfigure and no button to delete.
Any suggestion?
