Nothing else than the sample files open

I can open the “Dance Center” and “SketchUp Logo” sample files and they work perfectly, but any other model from Dropbox/local memory/3D warehouse does not open. The loading screen with the SketchUp logo simply keeps rolling indefinitely.

I am using SketchUp Viewer 4.0.1(715) on OnePlus 5T with Android 8.1.0.

EDIT: works perfectly on Honor 8 with Android 7.0.

how large are your files?

I have same problem. My file is 250kb

Can you upload the file here?
Maybe there is somethinvg in the file tgat prevents loading

I tried with a minimal example of a 3D cube, size 15 kB. No success.

It’s not the file. See the EDIT in the first post. Has to do something with the phone/Android version.
