Hi @David Schneider,
Thank you for posting your question in the Microsoft Q&A forum.
Based or your description, the behavior you’re seeing is due to the "Viewing chats, teams, and channels" setting in Teams app, which merges Chats and Channels into one list. If you prefer the classic layout where Teams are shown separately, you can switch back easily by following this:
1/ In Teams, click the three dots icon (...) next to your profile picture (top-right corner).
2/ Select Settings.

3/ Go to Chat and Channels.
4/ Under View, change from Combined to Separate.

5/ Restart Teams for the change to take effect.
After switching to Separate, you’ll see the Teams tab again in the left navigation, and you can manage members by selecting More options (…) > Manage team.
I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this.
Thank you for your patience and your understanding. If you have any questions or need further assistance, please feel free to share them in the comments on this post so I can continue to support you.
I look forward to continuing the conversation.
