There is one website that I can't get to work with the 1Password extension, no matter which browser I use. It is Hamburger Abendblatt and it looks to me like their overlay is not compatible with 1Password. However even on a subpage with another type of login form my login won't be autofilled. There is no difference whether I click on the browser icon and select "Auto Fill" or if I click inside the fields and then on my login. The problem occurs in Firefox, Chrome and Safari (all on Mac). I haven't been able to check on a windows machine.
Is there something that can be done on my end to fix this behaviour?
Thanks a lot in advance
