I changed the secret code to #1234*, and then I made a call with number #1234* to show the icon of the app again, but it displays the error message:
Error performing request. Unknown Error.
I am in Pakistan.
Answer: In most cases, the customers made a mistake to make a call with *1234# instead of #1234*.
Would you please start with symbol # firstly?
It will fix the issue.
