Hello! I understand that when you try to access the Pimsleur app on your Android 10 device using the WebKit browser, you see a spinning circle and the app doesn’t load at all. Let’s work together to get this fixed.

First, I want to ask a couple of quick questions to understand better:
- Is this happening every time you try to open the app, or just occasionally?
- Have you tried restarting your device or checking your internet connection recently?
- Did you happen to update the app or your device around the time this problem started?

Meanwhile, here are some initial troubleshooting steps you can try which often resolve this kind of loading problem:

1. Check Internet Connection: Make sure you have a stable Wi-Fi or cellular data connection. Sometimes a weak or spotty network causes loading to get stuck.

2. Close and Reopen App: Fully close the Pimsleur app (remove it from recent apps) and then open it again.

3. Clear App Cache & Data:
- Go to Settings on your Android device.
- Tap Apps & notifications > See all apps > Find Pimsleur.
- Tap Storage & cache.
- Tap Clear Cache first, then try to open the app.
- If that doesn’t help, you can try Clear Storage or Clear Data (this will log you out, so you will need to log back in).

4. Restart your device: Sometimes a simple restart can clear any temporary system glitches.

5. Update App: Visit the Google Play Store and make sure your Pimsleur app is fully updated. Outdated versions may cause loading errors.

6. Reinstall App: If updates don’t help, uninstall and then reinstall the Pimsleur app.

If you’ve already tried some of these, just let me know which ones, and I can guide you further.

Also, since you mentioned it’s a spinning circle on an Android device, this could sometimes be related to storage space or permissions issues. I can guide you on checking those next if needed.

Please try those and tell me how it goes or if you need step-by-step help with any of them!
