Hello. Make sure you have the latest updated A10(content manager) as the dev updated that issue you mention.
I used an Amazing free add on called Skydolly. I personally like this one the most as you can individually fly the aircraft in formation, which to me is more of a fun challenge, however there is a newer add on that has a free version called Air Assistant. That is a much easier way to do a formation fly over as you just fly one plane and the others are all set to mimic your moves. Easier, but to me not quite as rewarding.
It’s fairly easy to install and get right into it. https://flightsim.to/file/9067/sky-dolly
