If you are experiencing issues with the category filter not working in the Equinox+ app, consider the following steps to troubleshoot and resolve the problem:

1. Check for App Updates
Ensure you are using the latest version of the Equinox+ app. Go to your app store, search for Equinox+, and check if an update is available. Installing the latest version can fix bugs and improve performance - learn more.

2. Reboot Your Device
Sometimes, simply restarting your device can resolve temporary glitches. Turn off your device completely, wait for a few seconds, and then power it back on.

3. Clear Cache and Data
On your device, locate the settings for the Equinox+ app, and clear the app's cache and data. This action can help reset any settings that might be contributing to the filter issue.

- For Android Devices: Go to Settings > Apps > Equinox+ > Storage > Clear Cache and Clear Data.

- For iOS Devices: It may require you to uninstall and then reinstall the app to clear data, as iOS does not have a direct option for clearing cache like Android.

4. Test the Filter Functionality
After performing the above steps, open the Equinox+ app and test the category filter again. Try selecting different categories to see if the functionality has been restored.

5. Check Network Connection
Ensure you have a stable internet connection. Sometimes, connectivity issues can cause features in apps to malfunction. If you're using Wi-Fi, disconnect and reconnect, or try switching to mobile data to see if there's a change.

6. Review App Settings
Within the app, check if there are any settings related to filters that may need adjusting. Some functionalities might be disabled or configured in a way that limits their use - learn more.

7. Contact Support
