When you format a card as Internal Storage, you're not supposed to have to worry about moving apps or data between the phone's storage and the SD card, because the card is supposed to be completely incorporated into the phone's internal storage. But I know from many posts on this forum that Moto has always had an odd implementation of Adoptable Storage that can cause problems -- e.g., I've seen posts about how the phone will say that it's running out of storage even though there's plenty of room left on the adopted SD card. The bottom line, as mustang7757 mentioned, is that Adoptable Storage is not a reliable way to expand your storage. If you want to install a lot of apps, then your best solution is to upgrade your phone to one that has at least 32 or 64 GB of internal storage. Phones like the E5 Play are not flagships, and were not intended to be workhorses -- they're budget phones for basic use.
