Ikea Domsjö sink - drain stopper and strainer do not fit

Hello everyone,

I have installed a domsjö sink, with the Atlant siphon. However, the drain stopper does not fit into the screw that attaches the sink to the siphon (or vice versa). Is there something to consider that I missed, or do I need to make a complaint?

Have the same problem. Obviously, there are 2 screws. One short and one long. The short one fits with the [Sieb], the long one does not!? Whether the short one is long enough to fix the siphon, I will try today. In any case, extremely confusing :eek: :eek:
