Upload photos in background on Android?

Tresorit's Android documentation (https://support.tresorit.com/hc/en-us/articles/4404185404306-How-to-use-camera-uploads) says that you should be able to select an option to "Upload Automatically" and "upload in background" for photo uploads. On my phone, I don't have these options. My device shows only the following options related to camera uploads:

- Upload mode (New photos only / All photos) - What to upload (Photos / Photos and Videos)

Therefore, photos are only uploaded if I remember to open Tresorit and wait for it to do its thing. Does anyone know if the background/auto uploads featuers were removed? I'm testing Tresorit as I may switch to it from Sync.com but this may be a deal breaker for me. Thanks in advance.

*edit* - This was resolved. I had to change my battery setting for Tresorit from "Optimized" to "Unrestricted". It now automatically uploads photos, even after a reboot. Thanks for all the input!
