+## Known issues
+### Preview doesn't render in Brave
+This is caused by the device recognition shield in Brave. By changing the setting for "Device Recognition" in Shield settings to "Allow all device recognition attemps" or "Only block cross-site device recognition attemps" you should not get this error.
