Go to your Profile to make sure the notifications feature is still on.
Some browsers revoke permissions over time, or you may incidentally reject or revoke these permissions when updating browsers and settings.
Sometimes you (or an extension) may have muted the UPchieve tab. Right-click the tab and check if there’s an option to Unmute.
Browsers try not to allow sound all the time for security reasons and to avoid bombarding users with noisy ads. (For example, you can read a blog post from the Chrome team.) Sometimes this can get in the way of UPchieve notifications.
How to check that UPchieve has permission depends on your browser. Here are instructions for some common ones.
Paste chrome://settings/content/sound into your address bar.
Turn on Allow sites to play sound.
Then, next to “Allow,” click Add.
In the pop-up window, enter app.upchieve.org.
Click Add.
Go to app.upchieve.org.
On the left of a web page address, click the lock icon
Click Show connection detailss
Click More Information.
Click the Permissions tab.
Under “Autoplay,” uncheck the box next to “Use Default.”
Click Allow Audio and Video.
Go to app.upchieve.org
In the top left, click Safari > Settings for this website.
Next to “Auto-Play,” choose Allow All Auto-Play.
