Just an update from my side - after about 14 days, my DSA status was finally approved. It seems it just takes time on Apple’s side.

Hi, I’m experiencing exactly the same issue. My DSA status has been “In Review” for about 2 weeks now and it hasn’t changed at all. Did you manage to get approved in the end? If so, how long did it take? I’d really appreciate any info - this delay is blocking my app in the EU as well.
