I think at least Lufthansa is now accepting it. When I did my document check with them on Friday, they had a list of countries that are accepted for visa exemption and I heard them talk about it. I think it just took them a while to realise this is approved, which is terribly annoying of course.
I totally agree that the group helps and totally fine if people want to ask for clarifications and/or want to confirm things or get reassured. But there are some where you really feel they have not even tried. But overall so be it, the groups are still super helpful and it is what it is :)
I think the best is to continue to try and reach the embassy in the country you are in or are planning to apply from. It took me a while to get through too. Good luck!
