Can't view comments - "couldnt_get_comments"

Hello,

I randomly downloaded Connect for Lemmy, but I've never used apps on my phone for social.

When I try to view comments I get the error message "couldnt_get_comments"

I'm not sure what could be causing the problem. It makes the app worthless, but I don't want to give up on it if I'm doing something wrong.

Has anyone else had the error message and resolved it?

Thanks
