Hello, @Iggyp06. Thanks for stopping by. Whether the apps can be moved or not to the external SD card is determined by the phone's software version and the app version.
It can happen that the new version of an app will no longer allow the app to be moved. Also, your phone's software will stop an app from being moved to the SD card if it is necessary for the app to stay in the internal memory so that they can work properly without any damage or lagging.
called lg and they stated that when u update past android version 5 you can no longer move apps to sd card and photos can only be moved through file manager i am in process of trying to figure out how to downgrade android version as we speak
