HI, we have 2 iphones in the household on 48 but when accessing the app, they both get a message saying

"The certificate for this server is invalid. You might be connecting to a serverthat is pretending to be "m.48months.ie" which could put your confidential information at risk.

I spoke to an agent (because we couldnt add credit and was advised it was an issue with the phone. We managed to add credit by logging in to the main 48 site.

Have googled and tried out some of the suggestions (date and time settings and resetting fraud warnings on safari) to no avail. Has anyone any other suggestions or is there an issue with the secirity certificate for the app?
