I lost use of the app on chromebook

Has anyone else,who uses a chromebook, lost access to the app recently. Admittedly, it has been a few months that I used my chromebook. Now it's telling me to update the app but when I go to the Google play store, that's tell me that dnd beyond is no longer supported on my device. 

So here's my question. Is it a bug that needs to be patched, or maybe WOTC decided to cut off access, or is it coming directly from Google. The whole reason I got my chromebook was to be able to host game nights from that device rather than opening the website; I prefer downloading my books just incase the internet goes out mid session. 

Any advice would be appreciated. 

Game night tonight and just found out I cant play either 

This totally sucks, the whole purpose of the app is to be able to have a reference for the books when no WiFi is available  Telling someone the "Work Around" is to go to the website when they don't have access to the web is ridiculous.  I depend on that app to run games at local venues, charity events and conventions where the internet is either unavailable or so horribly slow and/or overtaxed.

This needs to be addressed or I will really have no use for the Master Tier Subscription since I will be forced to lug the books everywhere with me.
