Can't claim full Section 24 benefits for Noida property, what to do?

Did a deep dive into my property documents last weekend for tax filing. Yaar, it's so frustrating. My accountant just told me I can't claim full Section 24 benefit for my Sector 150 Godrej apartment's interest because of some OC delay. Builder ne bola tha sab clear hai. I've bought property before, but this is new. Kya aur kisi ne aisa issue face kiya hai? How did you guys manage it? It's like ₹50k ka loss annually. Koi workaround hai kya?
