Parallel passage references (\r) are not tappable

In the app I’ve just built with SAB 8.6.3 none of the parallel passage references (\r) are tappable. Paratext recognizes all of these lines as links, but the app does not. I tried adding, e.g. “|LUK 3:23” after the reference but that didn’t help. Is there something I need to do to enable the \r lines to work as links?

I’ve had this happen when SAB expected a different Chapter-Verse separator than what my Paratext project uses. To check this, with your book collection selected, go to the Features tab and look for the “Chapter-Verse Selector” line. In my case, SAB was expecting a period, but the Paratext project was using a colon.
