Default Verizon Galaxy S5 MMS

I'm having an issue on my Galaxy S5. If I use the stock messaging app MMS works fine sending and receiving. However if I use ANY other app including Textra and EvolveSMS, MMS always fails. I've tried tinkering with each apps settings but still no go. I would really prefer to use Textra but MMS is a deal breaker. The devs can't help but the fact that it is every app and only stock messaging sounds strange. What do you think?
