Unfortunately, you’re not giving enough information or being specific enough for me to be able to assist you, which I think is due to not understanding how our plugin works. Please review the documentation provided above and if you still have questions, open another ticket or join us on our Slack Chat at https://pods.io/chat/ and I’ll try to help out more.
