Some iOS users have reported an error, and until Apple releases a patch in a new version, this is how you can regain usage of Glossika sessions.
Please follow the steps below if you encounter: 1) iOS can’t load content; 2) constant error messages.
Step 2: Reset your iPhone
a) Close all your Glossika tabs, and delete any Glossika bookmarks you may have saved.
b) Please re-start your iOS device.
c) Open Safari on your iOS device.
d) Visit the Glossika page. You'll see a pop-up asking whether you'd like to turn on the microphone for Glossika -- please click "Cancel"
You should now be able to use Glossika sessions.
