New mobile and have been trying to sent up all my apps and keep having the same issue. App says I have been sent an authentication text to my mobile and nothing happens. For a few I have managed to use other options but I have quite a few ie steam (guard), discord, dropbox and so on that are stuck.
I have read that sending at night vs sending in daytime can be an issue but does any one have ideas on a fix or know if this is a vodafone thing?
