Mine experienced shakiness on GoPro approved, tested and recommended card - SanDisk Extreme microSD XC 1, V30, U3.
The same one their support asked you to buy :-). I mentioned to you, they are on a fishing trip trying to convince people that something else beside their own h/w, firmware is at fault. It is not the case.
GoPro has problems which cannnot be addressed by changing SD card or battery in at least two areas:
I believe shakiness can be fixed in firmware. I do not know if overheating can be fixed in firmware - perhaps, or perhaps just bad processor design.
I could not prove, in my experiments on my GoPro 7, that freeze issues are unrelated to power supply. In my case, there was a strong and 100% connection between quality of power supply (e.i. various batteries in various tmperature conditions) and video freeze with audio. Again - I do acknowledge that your experience may be different and that my advice does not help in your case.

This is killing me right now! I'm putting together a video and found that just about ALL MY SHOTS are effected by this **bleep** bug. I've got example after example of footage with a frozen screen and recorded audio UGH!!!!!
Sadly, one of my subscribers looked to me for support on a camera to buy. He's wife wanted to buy him an 8 and I told him to have her save the money. Get the 7 if anything and be careful of this bug we are all having!
I can't believe I'm doing this right now but I have a video shot at a bike shop tonight and I'm packing up the GoPro Silver Hero 4's and leaving the 7 and 8 at home! WTH!!!! All that money put into these cameras and I simply don't feel confident using them.
Such a shame!

I have just purchased the Hero 8 Black and I am having exactly the same issues as discussed here, I used it today for a Cross Country running race, what I have noticed that on the fifth file Hypersmooth Boost comes off and on the sixth file it continues with Boost off then freezes on a video frame and the audio continues.
The remaining files are also frozen on one video frame, but audio is ok, camera set 2.7k 50fps on Linear, I did run the camera until the battery was flat and the battery is the new blue GoPro battery for the Hero 8.
