User testing with mobile tablets

For those who are using iPad Pro (especially the 2018 - 2020 models): Are you able to open large Sketchup files on the SketchUp viewer?

My 7th gen iPad crashes when trying to open a 400mb file, so I was considering to upgrade to a pro, but two people here wrote that they are not able to open large files with iOS devices (one, two)

I can open a 400mb and even a 550mb file with my budget Xiaomi smartphone. The iPad Pro is far more power, so I expected that opening such files wouldn’t be an issue for it, but it apparently is?

What are your experiences?
