iPad Air 4 “Liquid Detected” warning — charging issue

kah22

My iPad Air 4 (about a year old) has started showing the “Liquid Detected” warning when charging. It’s been kept upright in a warm room, and the warning has mostly gone, but charging is very slow and sometimes the alert comes back.

I’ve tried:

• Fully shutting it down while charging
• Using an Apple plug (cable may or may not be genuine)
• Letting it dry 18+ hour

I’m wondering

• Can non-Apple or non-MFi cables trigger false “liquid detected” warnings?
• Has anyone had this issue and managed to fix it without replacing the iPad?
• Any tips on which MFi USB-C cables work reliably with the iPad Air 4?

Would love to hear if anyone’s experienced this and what actually worked for you — real-world tips appreciated!

Thanks for any advice. I really don’t want to head off to apple if possible
