Why do my apps keep getring removed from my SD card?

[Android Central Question]

I have a LG Stylo 2, VS835, thru Verizon, running Android 7.0, with 16G of storage, &I added a 32G SD card. Any &all apps which I am able to move to the SD card I do, but random apps somehow randomly keep getting moved back to my phone's storage &I have to go back thru every app to see which is &is not on my SD card, &if they are not I have to move them back to my SD card. Apps that I can move to SD card are Facebook, Messenger, Microsoft Word, Scanner Radio, Broadcastify, HP ePrint, Star Walk2, Google Translate, One Drive, Photo Grid, Zedge, iSnapxRemote, HP Print Service Plug-In, Google Earth, Facebook's Hello, Adobe Acrobat. How can I get this to stop?

It's not "random". While Android allows you to put portions (yes, only portions of the app actually move) of apps onto the SD card, it can't update them while they're still there. During app updates, the SD portions get put back to internal storage so the app can be updated but then it's up to you to put them back.

Unfortunately, that just happens to be the way it works.
