Update this filter now button

### Problem Description

When I click the update button in the right up corner, it is not update all of my filters immediately, but it is showing "you are using the most recent versions of filters." For example, it is not update the [hufilter](https://raw.githubusercontent.com/hufilter/hufilter/master/hufilter.txt) list in the first 2-3 hours.

### Proposed Solution

Please check this problem out, and if it is possible, please add an "Update this filter now" button to the "filter page" (For example: Settings > Content blocking > Filters > Language-specific > hufilter page)

### Additional Information

I'm using Adguard v3.3 beta 3.1 (188) on Samsung Android 9 Pie.

Thanks in the advance.
