Good day everyone! i just bought Sandisk Extreme Pro 128 GB yesterday and I installed it in my DJI Mini 2 Drone. But when I started recording in 4K i got a sd card error saying "SD card speed low. Normal use maybe affected. Backup files and format or replace SD card."  If I set my camera in 1080p seems no problem. It is so frustrating that i can't record in 4K mode.

I have the same issue and found out through an SD card testing app that the card I bought Sandisk Extreme Pro 64 GB is a fake. Apparently there are a few online stores including Amazon, Lazada and eBay are unwittingly selling them without knowing they are fake. https://prnt.sc/e4uxjwQTaVJc

Hey bud! I already found the problem and you made it right! My SD Card was the problem. I purchased earlier a legit Sandisk Extreme sd card and it works great! I can record 4k now.
