@Doobee - If you use Chrome, there's an app you can download called VisualPing. You can set it up to notify you when there's been a change on a web page. I use it for Prolific and have noticed the difference.
If you don't use Chrome, I suspect there are other similar apps for other browsers.
For Firefox you can use the Distill Web Monitor Add-on and it does the same thing.
I use it and it works well.
Thank you. I've been using Auto Refresh which was working really well although silently. Hopefully, this will work better. If I don't hear anything today, then I'll know they're purposely not sending me any.
