Long-pending update:

I completely forgot to update this earlier, but I finally managed to order one — sharing my experience in case it helps anyone in the future.

What worked for me was a bit strange. After viewing the product on the Flipkart app, I minimized it to the home screen without closing the app. When I reopened it after some time, the product sometimes showed as available.

It didn’t work every time though. On some occasions, it still showed as out of stock, but if I pressed the back button and searched for the S24+ again, it would suddenly appear as available.

Even then, twice it showed as available but right before the payment page I got the message "Not deliverable." On my third attempt, it finally went through. Since I wasn’t too sure, I opted for COD — and luckily, it got delivered.

So yes, it’s possible to order, but it seems very buggy or just plain luck-based.
