I'm amazed that Android doesn't have a built in way to connect to a network drive like iOS/iPadOS has
I have a TrueNAS server at home and thought I could easily connect it to my phone (Pixel 7) as a network drive but was surprised to learn that Android doesn't have a built in feature for that.
iOS/iPadOS does have this to my surprise built in via the 'Files' app.
Or did I just not look hard enough in the Android settings? (I know there are 3rd party apps for this)
The stock files app is lacking to say the least. Try Material Files and optionally Round Sync which will allow you to access all rclone supported remotes in the material files app.
