Hi 

I bought Sandisk SD cards and tried to insert them but the camera keeps on telling me that " Invalid format"/

I have formatted the SD card to FAT32 but still the same error. 

I get a troubleshooting step that Card should be formated in APP. but I do not have an option to format on the app. 

After I got " Storage and Recording" I only have  "Micro SD card  - NO SD Card but there is no option to FORMAT> 

I tried to contact Technical support but no one responded, I have written multiple emails but no response. I am at risk with no events getting recorded. Please help me.
