I have this problem with the App for an year or more. I never receive the SMS with the code, as well as the “Phone call” option. (it worked a few months before the Crypto update)
Even tho your chat support is terrible, as well as the app chat itself, I used to “fix” this by contacting them to give me a correct code to login.
Now the “Send” button in my App is grayed out (disabled), so I cannot send my message to the support. I tried to remove the app data and reinstall the app, but with no luck.
