@userwhat, thank you for your prompt response. Put simply,
- Group messaging is a basic feature of MMS.
- Mudita advertised MMS as a feature of the Kompakt.
- But, Mudita delivered Kompakt with crippled, buggy MMS.
- So, Mudita delivered a product that was not ready for launch.
Given that Mudita cannot even hint as to when MMS will be fully functional, I will ask Mudita Support for a refund.
MAJOR UPDATE: After experimentation with the sideloaded Quik app (Hat tip to @gezimos for suggesting it!), I have decided that it sufficiently replaces the missing MMS features in Kompakt’s buggy SMS app. And, I have decided to take a chance on Mudita making the SMS app fully functional – both bugs-wise and missing-MMS-features-wise – eventually … and hopefully in the release after the July release! So, I am keeping my Kompakt and have asked Mudita Support to close my refund-request ticket. (Now I must train myself NOT to tap the SMS app’s icon on the home screen.)
