Hello! I understand you're experiencing an issue with a white dot appearing on product pictures, and that links aren't working in the LTK app. Let's work through this together.

### Step 1: White Dot on Product Pictures
The white dot on product images may be related to how the app is rendering content. Here are a few things we can check:

1. Clear App Cache: Go to your iPhone's Settings > General > iPhone Storage. Find the LTK app, select it, and choose "Offload App" to clear its cache. Then reinstall the app from the App Store.

2. Update the App: Make sure you are using the latest version of the LTK app. Open the App Store, tap on your profile icon at the top right, and scroll down to see any available updates.

3. Check Internet Connection: Ensure that your Wi-Fi or cellular connection is stable. You can also try toggling Airplane Mode on and off to refresh the connection.

### Step 2: Links Not Working
For the links not functioning, let’s try the following:

1. Reboot Your Device: Sometimes a simple restart can resolve connectivity issues. Press and hold the side button until you see the "slide to power off" option, then turn it back on.

2. Check Link Permissions: Make sure that any necessary app permissions are granted. Go to Settings > Privacy > Local Network and ensure LTK is allowed.

3. User Account Check: Log out of your LTK account and log back in. This can refresh your session and fix any underlying issues.

### Step 3: Further Assistance
