Android without images on menu

[Zellogie]

Can't seem to see any menu images, like the settings button or back from folder (see image below).
Using Png on server works fine. Tried to locate if there was any folders on the phone itself, but only found one empty folder(com.streampi.client).
Double checked that the app got permissions to read/write, even a factory reset and reinstall the apk.

Not sure what else to try.

Here's the versions etc.
Phone: Huawei P20 running android 10 stock.
Pi client: android-aarch64-2.0.0-SNAPSHOT.apk

Server atm: Linux mint 20.3 cinnamon
Server Stream-pi: stream-pi-server-linux-x64-2.0.0-SNAPSHOT.deb

Let me know if you need anything else! Or if I'm missing something obvious.. :)
