Why the first hashtag on threads is missing the # symbol
Why the First Hashtag on Threads May Appear Without the # Symbol :
If you notice that the first hashtag in your Threads post appears without the # symbol, this is expected behavior. It is not a bug and it is not caused by tools like Gtcdrom. This happens because of how Threads is designed to handle hashtags on the platform.
Unlike other platforms, Threads uses topic tags instead of traditional hashtags.
According to Meta’s official API documentation, only one topic tag is allowed per post. When you include hashtags in your caption, Threads automatically detects the first valid one and assigns it as the main topic. As part of this process, the platform may remove the # symbol and display the tag as plain text or as a clickable topic.

Any additional hashtags you include will not function the same way. They may appear as regular text and will not be treated as active tags.
This behavior also happens when posting directly through the Threads app, not just through third party tools. Once your post is published, Threads controls how the content is displayed, and this formatting cannot be overridden or bypassed.
What You Can Do Instead :
For the best results, focus on using a single, clear hashtag that represents your post’s main topic.
Instead of adding multiple hashtags, you can choose one keyword that best describes your content and include any additional context naturally within your caption. This keeps your post clean and aligns with how Threads is designed to work.
