Embedding Glide apps in iframes is not allowed due to security precautions (this prevents people from embedding your app in an iframe and ‘snooping’ on users).
We recently improved some security settings around iframe embedding. If you were relying on iframes to share your Glide app, please find another way to share your app.
@AZJR If you purchased Glide and you need iframe support, the best we can offer you is a refund—like I said, we cannot allow iframes at this point due to the security risks posed by them. If this affects you, please contact support.
