Problem logging onto Datadear website and using the new 365 add-in

This morning while trying to logging onto DataDear website I get message about expired security ceritifcate. So this needs to be fixed.

I usually have datadear excel add-in for HMRC added but this morning when I opened Excel, I got message about failure to load with possible reason of internet unavailability. I noticed the new 365 add-in available so installed that. When I try to activiate the add-in from Add-in tab, I get a message that “Content is blocked because it isn’t signed by a valid security ceritifcate”.
Please look into this and fix it so that I can use the add-in to complete my VAT return.

Thanks,
KN

I came into work early this morning and have struck the same problem.
Can’t log into the website because of the error you described, and I can’t use the Excel Add-in either.
I have tried the old one and the new one… hopefully the support team can get onto this quickly.
