Troubleshoot Common Issues
When the linking process fails, identify and fix the issue based on symptoms.

Link Not Saving
- Confirm that you hit “Save” or “Done” after adding your Instagram.

Instagram & TikTok Link Policies and Restrictions
Both platforms set clear guidelines for allowed placement and functionality of links.
Key Rules:
- TikTok disallows clickable URLs in video descriptions.
- Instagram blocks certain domains to prevent spam.
- Direct cross-linking between platforms is only available in particular profile sections.
| Platform | Clickable Areas | Not Clickable |
|---|---|---|
| Bio link, Story links (if eligible), Direct Messages | Feed captions, Comments | |
| TikTok | Social link field in profile, Bio (if eligible) | Video captions, Comments |

Using the Official TikTok Link Field vs. Alternatives
TikTok’s built-in “Add Instagram” feature is the most dependable integration.
Alternative: Bio Link Services
If native linking fails, consider a multi-link tool such as Linktree or Beacons.
Pros:
- Consolidates all your important links, including Instagram.
- Offers click analytics.
Cons:
- Adds an extra follower step.
- Lacks the native social icon display on your TikTok profile.

Clear Cache and Restart Apps
Residual cache files can cause glitches.
On iOS:
- No direct clear-cache option—uninstall and reinstall the app.
- Or go to Settings → iPhone Storage → Offload App.
On Android:
- Navigate to Settings → Apps → [App Name] → Storage.
- Tap Clear Cache.
Restart the device before retrying.

Remove and Re-add the Linked Account

- Wait a few minutes.
- Repeat the linking process.

Test on Different Devices & Connections
Rule out device-specific issues by:

Update or Reinstall Apps
For stubborn technical issues:

Include:
