All I see at the osmand web site is a forum. . .
There are a number of things that seem to have broken on the 1.7.3 and 1.7.4 releases (haven’t checked 1.7.5 yet) and rather than create more noise if they know about them I’d like to check to see what other others have reported.
In the meantime I’ve loaded 1.5 from fdroid to get me back to something that works for me.
