I just feel like you do not have any more passion for developing AdGuard and here are the reasons:
1. AdGuard Assistant 4.0 still in the same state.
2. Fewer updates.
3. There are many bugs, for example, no icon for Vivaldi browser on adGuard Moreover JW Player Ads are not blocking by AdGuard I can only hide them but the voice is still there.
4. Crashes and slowdowns on Edge browser when AdGuard is running.
I am using the latest version with AdGuard extension on Vivaldi Browser.
