Now, I'm facing similar issue
X, MobiKwik, Aadhar and few other app and website including the picture loading in both of our forum are not working from yesterday morning on my "Jio" sim whereas "WiFi" connected through another "Jio sim" via hotspot is working "smooth".
I've tried resetting APN, resetting network, switching slot, no VPN running and what not nothing work in favour.
Contacted CC twice, no improvement till now.
