Still have same issue. Actually, the SIM card icon alternately displays the card with an "x", or bars with an X above them.
Still haven't been able to connect, however.

Thanks Paul,
Yes this issue occurred only after App forced an update to current version. Up to date.
Yes, several bars - signal is strong.
