App Usability is Inconsistent

Update: 3 days ago a new update came out and the app is even clunkier than before. Everything has a delayed action, comments won’t show when there’s more on the thread, and you can’t react to comments. They really need to figure out what’s wrong.
This mobile app has several issues that haven’t been addressed, and seems to be becoming more difficult to use from a software standpoint. Scrolling in the app is very slow and more often than not it freezes. This is also apparent (as others have mentioned) when you try to add a reaction to a post/comment, it doesn't allow you to do so. Another issue I’ve noticed this for several years and notified the help center (to no avail), is when you scroll through the “Finds” section for more than a few seconds, it heats up your phone significantly. Overall the platform is what it is with regard to social media, but focused more on your immediate town/neighborhood for updates and questions. Unfortunately, there can be a lot of cruel neighbors, but it’s a resource to better to know and avoid those who treat others poorly. Those who complain about “free speech” are the ones neglecting the fact social media is a private business that can regulate offensive and malignant content.
