Do Shopify Apps Work With The Bilingual Theme?

In general, Apps will work with our theme, in terms of functionality.  For example, it is possible to set up "Customer Pricing" with our theme, so you can set different pricing levels for different groups of customers.  That will work.

What sometimes does not work, is text that comes as part of the App.  For example, if there are headings, text or menus that come with an App, it's often not possible for us to make them switch bilingually, as we're not able to get 'inside' the app (since it belongs to another developer) to make it bilingual.

So, to sum it up:  Functionality is generally compatible, but there are cases when sometimes we can't make text switch bilingually, like it does in the rest of our theme.
