Sport mode will not disable the bottom sensor, only horizontal. To disable all sensing go to Settings-Safety-Advanced Safety Setting, at the bottom turn off Vision Positioning and Obstacle Sensing. Read warning explaining what it does and press...
I'm not sure how "set iso to auto and don't be in DLog" isn't clear, but if it doesn't make sense then just go full manual and the camera will work as it always did.
I ordered a Mini 5 Pro Fly More Plus combo from Korean seller "102_store" on eBay late night on Thursday 11/27 (Thanksgiving night), like around midnight (Pacific time). It was delivered today, Tuesday 12/2. Not too shabby for coming from Korea...
I totally missed the PLUS when I was searching and ordered. I'll pick one or two up after the holidays. I'm excited that I could get the 5 before they could possibly become unavailable.
