Lightroom Mobile: Raw image import on Chrome OS
The latest Chrome OS release (77) now uses the native files window within Android apps. Unfortunately, in Lightroom the file formats are filtered to a range of image formats that don't include .NEF. There is no way to change the possible formats and this means that it is currently not possible to import raw images. I've contacted google support about this but they say the responsibility lies with the app developer. I am using a Google Pixelbook.
