Just uploaded a new version of my app to beta with the new Downloadable Fonts and Fonts in XML features and the pre-launch report from google is showing me crashes on some devices.
LG G6, Android 7.0:

I noticed in the report videos that those crashes are occurring in the first screens of the app but when i run the app myself on an emulator or a real device (Oreo or pre Oreo) this crashes dont happen.
Also, as a side note, but i think its related, i've been trying to use
<meta-data android:name="preloaded_fonts"
android:resource="@array/preloaded_fonts" />
in AndroidManifest.xml but it doesnt seem to work at all. when trying to access a font, either via xml or by code, the app crashes because the font isnt being recognized. So i decided eventually to remove this meta-data.
Help is appreciated.
