I’ve been trying to find a way to force install apps onto my SD card and I found many options such as “Force Allow Apps on External” or formatting the SD card to Internal storage. Neither of these options have worked so I’m trying to find a workaround (can provide images)
Have you tried https://stackoverflow.com/questions/38044532/how-to-turn-a-portable-sd-card-into-internal-storage-via-adb-command? Make sure you don’t allocate all into internal, leave some for external since some apps assume they always exist and crash otherwise.
