Will not open !!!! – Yomi's Medical Dictionary - Medical Terms Review

I've used in the past, with good results. Tried to use today and the app will not open. ? Something to do with recent update? Otherwise, would give higher stars, but deserves a few stars for content and developers are trying. Although, if this is a wide spread event, not sure how this was missed. ( To be fair, I have absolutely NO clue how these things even work) Revisit when problem fixed.
