The problem is not the software, as the software works as designed and advertised. The problem is that Agilebits will remove a popular feature despite customers objection. They seem to want to push users to their new paid subscription model, and may be removing free features to facilitate it. Point in fact, just after introducing their paid sharing feature, they removed a long standing feature that allowed free sharing through iMessage. It really calls into question whether other existing free features will end , only to be migrated to a paid subscription. So, be careful. What you get now may not be what you will have down the road.
