Hello,

where is the error?
In case you mean the warning, then you can ignore it, as long you do not need nothing mentioned in the warning, for example on black *day 2046-05-13 every user will %&$§& you.
see tsa -> time stamp authority.

Best xmas, anna-liebt

Google, Bing etc is your friend, because I am also beginer with this things.
You can deploy your apk, but users are not able to start the app after the date mentioned in the warning.

Best regards, anna-liebt

Well, I’m also getting the same warning. In my case, by mistake, I entered the wrong password more two times, so only I started receiving this warning. I’m also a beginner.
