Welcome to the forums, @rbsts1.
Assuming you are referring to desktop apps (not mobile apps), this is where you went wrong picking Bitwarden as your first password manager. Bitwarden currently does not offer 100% functionality for logging in to desktop apps — for example, one of the most upvoted feature requests in the forum is Auto-type/Autofill for logging into other desktop apps . Although Bitwarden developers are in the process of researching options for implementing this functionality, there are inherent challenges in how to do this in a way that maintains cross-platform compatibility and works using the Node.js package.
This, and any other frustrations you may have encountered (besides the inability to autofill when logging in to desktop apps), seem to be caused by either some idiosyncratic issue with your particular set-up (which you should be able to troubleshoot with help from the community of these forums, or by contacting Bitwarden’s tech support directly), or by a lack of knowledge on your part regarding how to most effectively accomplish various tasks within Bitwarden’s UI (which you can also get help with on these forums).
Just like switching between a PC and a Mac is not intuitive and would require a learning curve, it will take a little time to figure out the best way to work with Bitwarden if you are coming from a different password manager (including the password managers that are native to various browsers). To learn, all you have to do is to is post a question in the “Ask the Bitwarden Community” forum. For example, new users commonly ask for help when Bitwarden fails to provide login credentials to a specific website; this is usually easy to fix by modifying the URI matching rules or be defining custom fields.
If you absolutely need to autofill login credentials for desktop apps, then you should probably look at alternatives to Bitwarden. On the other hand, if autofilling in desktop apps is not essential, then you should be able to significantly improve your experience with Bitwarden if you start engaging with the user community on these forums.
