Hi! I understand you're experiencing an issue with TikBoost not delivering the desired number of subscribers. Let's work together to get to the bottom of this. Could you tell me a bit more about your campaign? For example:

- How long has the campaign been running?
- Are you seeing any error messages or delivery notifications?
- Have you noticed if the subscriber count is stuck at a certain number or just very slow?
- Are you targeting a specific region or audience?

This info will help me narrow down the cause and suggest the best fix.

Meanwhile, here are some common checks you can perform:

1. Campaign Status: Make sure your campaign is active and hasn't expired or been paused.
2. Audience Targeting: Sometimes, very narrow targeting limits reach and subscriber growth. If your targeting is very specific, consider broadening it slightly.
3. Budget and Bidding: Confirm your budget is sufficient to achieve your subscriber goals and that bids are competitive.
4. Content Quality and Compliance: Ensure your promotional content meets TikTok policies and hasn’t been flagged or is under review.
5. Platform Issues: Occasionally, delayed delivery happens due to platform-side delays or technical issues.

If you've tried these or can share specifics, I can help you troubleshoot with more tailored steps.

Are you comfortable sharing any details? That way, I can guide you thoroughly.
