We have an open ticket to fix this. In the meantime, if you add a site to your SafeListed Websites, it will fix the error.
In the Parent Portal, select Web Access from the Device Info tile.
You can also select Setting (1) and then Web Settings (2).
Scroll down and select Manage SafeList Websites.
Enter the address of the site you want available and select Add.
Note: In some cases, we've found it best to first visit the website you're adding on your own phone or computer to make sure it's the right site. Then copy and paste the site address into the Parent Portal. When you select Add, all of the extra parts of the address we don't need will be automatically removed.
In some cases, the site may add to the list twice. This is normal
Try using both shortcuts on the phone. If one doesn't work, simply remove it in the Parent Portal. If they both work, remove whichever one you want so the phone only lists one.
