It's frustrating when a feature like WiFi calling stops working after an update. Since you've already tried resetting your network settings and APN settings, let's explore other possible solutions.
First, ensure that WiFi calling is enabled on your device. You can check this by going to Settings > Network & internet > Mobile network > Wi-Fi calling. If it's not enabled, toggle the switch to turn it on.
If WiFi calling is already enabled, try restarting your router and device. This often resolves connectivity issues. Additionally, check that your WiFi connection is stable and strong. A weak signal might be causing the problem.
Another possible solution is to check with your carrier, Jio, to see if there are any issues with their WiFi calling service or if they've made any changes to their settings. It's also worth ensuring that your device is running the latest software, as updates often resolve bugs and issues.
If none of these steps resolve the issue, you may want to consider performing a factory reset or visiting a authorized service center for further assistance.
