I just found out that in less than a month the version of talkatone I've been using won't be supported any more. They're insisting that I "upgrade". What exactly does that mean? Will it cost money? I've been using the free version. I wouldn't say it's great but ok. Does that have anything to do with the problem I've been having with it lately? It seems no matter what number I try to call it's "waiting for answer" and after about a dozen rings it shuts off with no answer.
