IHD not showing Gas usage

It’s been a week since I had smart meters installed, originally the IHD showed Gas and electric usage for about an hour, since then it only shows electricity usage. I’ve contacted bulb who sent a link to reset my connection, which I’ve tried twice, still no Gas usage. I’ve tried switching the IHD off overnight, still no Gas usage shown. In the mobile app I no longer have the option to submit readings for Electric and it shows readings from smart, but gas still appears to have the option to submit a reading. So any help on connecting my Gas usage to the IHD would be appreciated.

Same problem here, now my ihd has frozen and wont even switch off…frustrating
