I have a Moto G5 with 16 gb internal storage and a 64 gb SD card. 40 gb of the 80 gb total is full, with more than half of the SD card free but only 500 mb of the internal shared storage free, and I'm getting the "Storage space running out" notification and I can't install/update apps. I'm assuming I'm getting the notification because the internal shared storage is nearly full, but as the SD card is formatted as internal and has lots of space surely it shouldn't matter?
