Why Isn't the "Use on Both Phone and Tablet" Option Visible in WeChat for Android?

If you don't see the "Use on Both Phone and Tablet" option in WeChat for Android, it's likely due to your device's resolution settings. WeChat automatically hides this option on devices with a resolution below a certain threshold.

To fix this, try adjusting your device's resolution scaling to 100% or lower. This might increase your device's resolution, making the tablet login option visible again.
