Hell no. I applied for citizenship over a year ago now and no communication has been made with me. I'm also not sure where this "up to 10 months" is coming from because when I applied (and recently checked) it says "over 2 years". On top of that I'm not sure what reddit you're looking at, but the ones I'm looking at are constantly complaining about how long the process is taking - how they expected it in 2022 and are still waiting in 2024.
Also this "web ui" is so bad and difficult to work with. I lost all the data I input at least twice, also the forms do no seem up to date with the requirements (requirements on newindenmark are different from what is presented on the form).
The official website says the wait time for permanent residency is "up to 10 months", and searching Reddit suggests 3-6 months is more normal.
Denmark is not particularly welcoming to immigrants, but they do with rules rather than inefficient paperwork.
