Yes - it all worked fine before.
The only seatmaps on Lufthansa Group which work for me now are shorthaul Business and longhaul First (with a wrong seat layout).
Everything else on LHG still seems broken.

I got the "we're working on it" reply from EF last Tuesday, promising updates on the progress, as well as next steps about my subscription.
No news since then, so I've cancelled my auto-renewal.
