Insufficient Storage - SD Card used as Internal Storage
What error does Google Play Store give. Insufficient storage? Or any other. And could 36GB be insufficient? Please note that application package rests on /data/app which is obviously internal, then all it's data is got in the sd. That means you may encounter that error if internal storage is below 15% of it's original size no matter how massive is your external sd. If that isn't still the issue, I think that's a bug in the Lineage OS you're running. I'm running lineage too. That feature works perfect like on any AOSP
