Hi there! I understand that having to sign in to the LES MILLS+ app every day is inconvenient, especially since the old on-demand app didn't require that. Let's see what we can do to fix this for you on your iPhone running iOS 26.3.1.

Here are some steps to try that might help stop the app from logging you out daily:

1. Ensure the app is fully updated:
Go to the App Store and check if there’s an update available for LES MILLS+. Sometimes updates fix login/session issues.

2. Check your device’s background app refresh and network settings:
- Go to Settings > General > Background App Refresh and make sure it’s enabled for LES MILLS+. This helps keep your login session active.
- Also, ensure your internet connection is stable, whether on Wi-Fi or cellular data.

3. Avoid signing out manually:
Try to stay logged in without signing out; sometimes manual sign-outs force daily re-logins.

4. Log out, restart your iPhone, and log in again:
- Open the LES MILLS+ app and log out.
- Restart your iPhone by holding the side button and volume up/down until you see the “slide to power off” option, then power it off.
- Turn it back on and open the app to log in again.

5. Check for any security settings on your LES MILLS+ account:
Sometimes apps log you out automatically if it detects unusual activity or security concerns. Visit your account page on the LES MILLS+ website and ensure there’s no suspicious activity.

If you've done some of these already or if that doesn't resolve the issue, there could be something else going on at the account level or with app session validation.

Would you mind letting me know if you’ve already tried any of these? That way, I can guide you through more advanced steps or account checks.

Are you seeing this daily log-in on other devices as well, or just your iPhone?

Looking forward to your reply!
