You didn't answer any of my questions, but you did give me enough information to solve this for you.
Basically, Google is stupid and bad. They won't let you make a link to a specific thing that you open as a link on your homescreen.
The solve:
- You go to a url shorting site, like tinyurl, and make a custom link.
- you put your phone into airplane mode
- put the new url into firefox, and once the page doesn't load (no connection) you add it to your homescreen like normal. This re-direct will stop google from thinking that you opened the link as a homescreen shortcut.
- close all browser tabs
- turn airplane mode off (so you have connections again)
- complete
- Optional but recommended: Uninstall Brave
Looks good!
But if you want to use the posts for play, you'll likely want to connect them with rails at the top
