Please help, I have a P4 and have my flight assessment tomorrow. I have a software update on my tablet, so followed the link etc. The software updated onto the tablet and then asked me to connect it to the P4, I did and then clicked onto the upgrade tab. After a short while, it said it could not update and then requested I created a report which then is sent to DJI, at no point has it told me the problem, nor have I received anything from DJI. Hope this make sense and that someone can help me. Kind Regards Dave.
