Westminster Chimes App Question

iOS and iPadOS
Using iPhone 4S, running 6.0 & using the paid version of Westminster Chimes. Does anyone know how to get voice over to announce the time when Westminster Chimes sounds the hour & half hour? This use to work for me, but after the last couple of upgrades it no longer performs this action. I've followed the developer's instructions noted in the app & only have sounds turned on. Also have selected "some punctuation" in my roter. Is there some additional setting required (either in Notifications, the app or somewhere else) to get the time announcement back? I sent a note to the developer & haven't received any response. Would appreciate any suggestions, advice, instructions, etc. those using & familiar with the app can provide. Thanks.
