Hi there! It sounds really annoying that the Acellus app keeps logging you out and crashing. Let’s get this sorted out together. To start, could you tell me:

- Are you using the latest version of the Acellus app?
- When exactly does the app crash—right after logging in or during use?
- Have you tried any fixes so far, like clearing cache or restarting your device?

Knowing this will help me pinpoint the issue better.

Meanwhile, here are some simple steps you can try:

1. Update the App: Make sure you have the latest version of the Acellus app installed on your Windows device. Older versions can sometimes cause crashes or login problems.

2. Clear Cache and Cookies: Since you mentioned WebKit browser environment, clearing your browser’s cache and cookies can resolve conflicts that lead to crashes or unexpected logouts. To do this in Windows:
- Open your browser’s settings.
- Find the Privacy or History section.
- Select the option to clear browsing data, including cache and cookies.

3. Restart the Device: A simple restart can refresh system resources.

4. Check Internet Connection: Ensure your internet is stable since interruptions can cause login failures and app crashes.

5. Try Incognito Mode or Different Browser: Sometimes, browser extensions or saved data cause issues. Incognito mode runs without extensions or cached data, so logging in there might work better.

If you’ve tried these already or if the crashes persist, please let me know exactly when the app crashes and I can guide you through more detailed troubleshooting steps or verify account settings.

Does this help so far? Are you able to try these steps?
