Hello Mark,
Thanks for your feedback even though we are really sorry for this experience!
We made a search to check if you opened any support issue and we could not find any! Are you searching for any specific feature that you could not find in our App ?
For the slowness, we have re-written the App via new technologies (Written in React) to make it faster, we are also continuously enhancing and improving the code to make it faster but sometimes when you are in the Atlassian Cloud, you can only rely on Cloud APIs and architecture to get data which can also cost time to load all the information. We are again sorry you had this experience and we would preferred you contact us on https://support.covectors.io/ to check how can make this experience better.
We remain at your disposal to discuss more and check how you can find your happiness with our App.
Many thanks
