It's NOT vanced bug/issue. It's youtube doing due to lockdown in various countries to limit data usage and huge traffic. So that every user can browse/surf on internet without much issues.
However, YouTube has lifted this cap in India for WiFi users only.
More info > here <
Now if you are looking for any workarounds to Bypass this, 1) You can try with VPN if you are lucky. YouTube applied this in most countries so you have to pick your new region wisely.
2) Watch on desktop mode [www(dot)youtube(dot)com]
3) Since the 480p restriction is only for mobile devices and not tablets we can change the model of the device in YouTube Vanced to overcome the restriction.
1. Open YouTube Vanced 2. Enable additional options by going to Settings -> Vanced Settings -> Tap on the About section till you get a message saying hidden Menu is visible 3. Go to Codec override -> Override model and enter the model number of any tab e.g. "SM-T865" and device to "Samsung" 4. Restart the app and the 480p limit should be gone now 5. Enjoy
Please note: • Anything happens on YouTube, happens on YouTube vanced since everything is controlled by server.
• We have no part and no control to remove this cap fully. So please don't ask how to fix it fully. Also, please don't ask when will youtube lift this cap as Google/YouTube are the only ones who knows. So don't waste time of us. Peace
