Hi,

To address this issue, you can store your data in the cache using the following steps:

Step 1:
You can utilize the onWillDestroy hook to save the current page's values when you navigate to another page.

Step 2:
Inside the onWillDestroy hook, set the cache values.

Step 3:
When returning to the previous page, retrieve the values from the cache.

Here's an example of how to implement this:
import { onMounted, Component, onWillDestroy } from "@odoo/owl";

class TestComponent extends Component {
    setup() {
        onWillDestroy(async () => {
            // Prepare values for caching
            const values = {
                time: this.time,
                content: 'Demo Content'
            };
           
            // Store values in local storage for potential resumption
            await browser.localStorage.setItem('AnalyticCacheResume', JSON.stringify(values));
        });

        onMounted(async () => {
            // Retrieve cached values from local storage for initial timer setup
            const values = JSON.parse(browser.localStorage.getItem('AnalyticCache') || '{}');
           
            // Log the retrieved values to the console
            console.log(values);

            // If you need to remove the cached data, you can use:
            browser.localStorage.removeItem('AnalyticCacheResume');
        });
    }
}

Note:-Change the owl hooks according to your use case.Please refer the below link to know more about owl hooks
