Updates for ARM Architecture devices

Not sure if this is the correct to post this but -

I've got a chromebook which has obviously chrome OS, but an ARM architecture, and so the only option I have for this is an older version of musescore 2. The later versions are not available apparently.

This works great on its own, however when I want to open files from my pc (which has musescore 3) on it for working while travelling, I can't, because the files will of course not work.

I appreciate this is probably a rather niche problem but it would be nice to have regular updates for this! :)
