Was using the free version for months, have recently purchased the monthly subscription. Today when I logged in I noticed that individual conversation deletion buttons, which were at the right of each conversation, were all gone and only one option to "Clear conversations" was available. While I try to keep my number of stored conversations to only a few, when I am testing new prompts before using them in a conversation, I need the option to delete them individually while maintaining my previous continued conversations. A fellow ChatGPT Plus user also noted that all of her individual conversations buttons were gone as well.
