Is it normal for salary negotiations to take over two weeks?

I interviewed with a company and received a job offer two weeks ago. The recruiter mentioned that the hiring manager was very impressed with me, but I later found out that the top salary band for the position is $11k lower than my current salary (which the recruiter hadn’t mentioned before). I decided to negotiate to see if they could match my current pay. The recruiter seemed to anticipate some negotiation and assured me that the hiring manager would have some flexibility and would get back to me.

However, it’s been two weeks since then and I haven’t heard anything. I reached out to the recruiter last week, and he promised to follow up by the end of the week, but I still haven’t received any updates. Is this typical for salary discussions to take this long? I’m starting to feel frustrated with the lack of communication.
