Hi there! I see you're having trouble with the MANGA Plus app—it keeps loading and then shows the message "Please try again later" when you switch tabs. Let me help you figure this out.

First, just to clarify:
- Are you using the app on your Windows system via a WebKit browser or a standalone Windows app?
- Have you already tried restarting the app or clearing any cache or temporary data?
- Does this happen on all tabs or just specific ones?
- Are you connected via stable internet, or have you noticed network fluctuations?

Meanwhile, here are some initial steps that tend to fix loading issues in MANGA Plus:

1. Clear Browser Cache (since you mentioned WebKit):
Sometimes cached data causes loading hiccups. To clear cache on a WebKit-based browser in Windows 10, go to your browser settings > Privacy or History > Clear browsing data > Select cached images and files > Clear.

2. Sign Out and Sign Back In:
This refreshes your session and can resolve token or session expiration issues that cause loading trouble.

3. Check Internet Connection Stability:
Since loading depends on network connectivity, ensure your connection is stable and try switching from Wi-Fi to a wired connection or a different network.

4. Try Incognito/Private Mode:
This disables extensions or stored cookies that might be interfering.

5. Update the App or Browser:
If you're using the browser, ensure it's fully up to date. If you have any MANGA Plus app or extension, check for updates.

If these steps don't help, a common cause linked to the "Please try again later" message is server-side session issues—sometimes caused by account conflicts or simultaneous logins on multiple devices/tabs. Signing out everywhere and then logging in again can help.

If you want, I can guide you through clearing cache or checking session refresh in your environment specifically.
