I'm having an issue in Go SMS where it will send MMS fine, but will always say it is unable to download any I have received. Strangely, it works fine when using the stock messaging app. I have done a thorough search on Google and XDA and have only found recommendations of altering the API or changing the settings within the app. I have spent hours researching and trying anything and everything. I've emailed the developers who have not yet responded to me and it's been two weeks. I left a negative Play Store review about their lack of assistance. Their response and proposed solution using their in-app method to help fix it doesn't function properly.
This is why I have come ask the magnificent XDA community to assist me in fixing this issue. This feels like my last resort.
I'm linking a logcat of the issue (I know that this typically contains the info of what the problem is, although I have no idea how to read one) in hopes that someone can at least tell me why this is happening and hopefully how to fix it.
