On the instance I’m using, my comments and posts have disappeared. It is ok?

I had a few helpful comments here that I saved, but it’s all gone.

Having got used to the stability in Mastodon I was surprised by such things in Lemmy as:

Unable to log into your account through the app after an update on the server.

Unable to log into your account through the app if your instance version is out of date.

Just because you’ve created a post or written a comment doesn’t mean other Lemmy users will see it.

I have to constantly check to see if my messages are visible on other instances.

You also need to have many sub-accounts on different instances in case some of the primary instances are unavailable.
