Updated 2022-02-18: My wife and I had been using this app for years using my Samsung Galaxy S7/J7 on Cricket Wireless (AT&T network). But around Thanksgiving 2021 we had to switch phones due to 5G compatibility. We now use Samsung Galaxy A32/A52 on Mint Mobile (T-Mobile network). Ever since we have not been able to send MMS messages. SMS goes fine, but MMS won't work. If it actually sends, it takes forever and the text is never received. Sometimes the message is received but the attached photo(s) are not. I've reached out to the developers with this issue with no response after four months. I tried again today and the issue remains. In fairness, I've reached out to Mint Mobile and they don't see any issues with the Network APN or other settings. Sad to have to not use this app anymore, but as many others have noted, the quality and support has gone downhill.
