<!--- Please read this! Before opening a new issue, make sure to search for keywords in the issues filtered by the "T - Bug" label and verify the issue you're about to submit isn't a duplicate. ---> ### Summary Reported by @ChrisDoogood We need to match the front-end for web and not allow members to edit media attachments in posts. This is because it causes major issues behind the scenes; one example problem is that on image change, all previous interaction is lost, presumably this happens for video also. ### Steps to reproduce 1. Make a post with an image. 2. Comment on the post. 3. Edit the image. 4. Note your comment is gone. ### Platform information Reported iOS, replicated Android (S10) likely platform agnostic. ### What is the current *bug* behavior? User can edit their image post so there are many things that break when they do this. ### What is the expected *correct* behavior? Disable editing of already posted images and videos. ### Relevant logs and/or screenshots (Paste any relevant logs - please use code blocks (```) to format console output, logs, and code as it's very hard to read otherwise.) ### Possible fixes (If you can, link to the line of code that might be responsible for the problem)
