RJapanese Not Grading My Recording PLUS Help Links Not Working

Note: I've contacted support.
Using Mac Chrome: ​Version 73.0.3683.103 (Official Build) (64-bit) (latest version)
I've cleared the cookies
I've restarted the Chrome browser
Problems:
1. After recording a sentence I get the following: "Sorry, I didn't catch that, please try again." However, clicking on the play recording button I can hear the recording. But there's no 'grading along with no completion".
2. All links in the help page don't work. I click on a link and nothing happens.

What is baffling is that it all worked so well before. It has been about 3-months since the last time I've used RJ. Something has happened to the website that will not give feedback grade when recording.

Just hoping I may find some suggestions here while I wait for support.

Hi Fillip, 

Thank you for your message; please note we have sent you a reply to your email address so we can review this problem further. 

The problem with the search box in the main site is currently being reviewed by our tech support team so it can be fixed as soon as possible.

Kind Regards

Could you PC perhaps not have a microphone enabled or not be using the correct microphone, it might be something in your computer settings to allow webpages to use your microphone.

Hi Tony,
The thing is about 4 to 5 months ago when I last used RJ everything worked. Nothing changed except the usual Mac OS updates. Now, like I mention, RJ does record my voice but there's no grading and I keep getting that "Sorry message".  

The good folks at support suggest I do the following which I did  with no success
1. In Mac Preferences -> Privacy > Microphone > "check box" next to Google Chrome to allow the app to access your microphone.
3. Reset Google Chrome > restart computer > launch Google Chrome 

It's baffling. I think I the only solution is to "live with it."  
Thanks for your suggestion. The RJ support team has been great. I understand there's only so much they can do.
