Please make devices cache embed mentions

As servers grow, it becomes increasingly more difficult to find specific users. On the mobile app, a very small of users remains cached. This can be bothering since it becomes very difficult to find or mention a specific member.

There is a way in which others can help each other: by mentioning members, it will cache them for everyone as they read the message. 

While this situation is not ideal, it becomes a nuisance when working with embeds. When you see a mention in an embed for someone who isn't cached for you, you will just see their user ID in a format like <@!123456789> or @invalid-user, making it very difficult to understand which member the embed is talking about. Developers, myself included, have to continuously find ways to ensure people can moderate even when the specific members aren't cached on their clients.

The solution is fairly simple: make devices cache the (users behind the) mentions in embeds as they read it, just like what already happens with text messages. That's it. That small change could make using embeds way more user-friendly and it would save developers a lot of time finding and building other (uglier) ways to make it work.

In addition, it would also be nice if you could actually click mentioned users in embeds to access their profile. While this is already the case on desktop, it isn't possible through the Android app.
