I'm not so surprised actually. Apple and Android use different font system.
This is why a while ago I suggested to embed a set of musical glyphs in iRealPro to avoid such situation so the charts could be identically displayed on both platform
Please use correct iRp chart-info format.
Example:
So Very Hard To Go (Tower of Power) - Emilio Castillo-Stephen "Doc" Kupka
...title.…………………….....(version)……… - composer(s)
