@suneth I was in a similar spot, and what helped me was an App Review appointment. I’d recommend registering for one.
The next available slots look like November 17-18. Requests are only open from November 8 at 12:00 a.m. to November 16 at 12:00 a.m. (PST), and the slots fill up fast, so the sooner you register, the better. I submitted my request at 12:01 a.m. when registration opened and got a 10 a.m. slot. Here’s the link: https://developer.apple.com/events/view/NLT5YC7N7L/dashboard
My app had been rejected several times, for a Business 3 subscription pricing question and separately for a Device Capabilities issue (Guideline 2.3). On the call, the Apple staff member confirmed the pricing concern was resolved and installed the app on both iPhone and iPad without any problem. He also moved my app up in the queue, and it was approved the same day.
Good luck!
