Absolute bummer. Sync was my favorite application while on Android - I actually enjoyed the features and user experience more than Apollo. The creator got dealt a bad hand when he released v20 and got absolute hate sent his way, but I’m hoping he at least realizes that he made a significant amount of Android users happy with his work.
I’m not opposed to it, as long as it isn’t intrusive and you have the option to turn it off. I know Signal introduced Stories (similar to Snapchat/IG stories), which is also a social media aspect in a messaging app, but you could outright turn that feature off and keep using it simply as a messaging app.
