    We would love to know what went wrong in your case and assist you if you could contact support. There are cases where if you have altered your JIRA permissions, our add-on and any other connect add-on cannot load. Or it could be a browser update that hide our plugin. In other words, causes could be many and our tests show the add-on to be working properly.

    Good product. It does what it says which is exactly what I needed and no other add-ons for Jira Cloud offer. It can be improved (especially the UI), but I understand that it's a new product and it's gonna take a while for the product to solidify. I had a problem with multiple formulas not working on the same project. I got a reply from Mumo Systems within half an hour of posting a request and was on a call with them in about an hour! In less than 1.5 hours after the call they provide me with a workaround so I can get going with my project with the promise to fix the bug for good.

    The add-on shows up in the projects, but when you create a basic formula using addition etc, it does not calculate the totals. Nothing at all happens. We contacted their support, and received no response.

    Paid-via-Atlassian pricing FAQ

    How does cloud add-on pricing work?

    Cloud pricing is subscription based. You are eligible for support and automatic version updates as long as your subscription is active.

    When your subscription renews each month, your pricing tier for host products and add-ons is automatically adjusted (as necessary) based on the number of users in your instance.

    If you've opted for annual billing for your host product, add-ons are also billed annually. Annual subscriptions for this add-on include a discount (12 months for the price of 10).

    If add-on pricing changes after your initial purchase, there's a 60-day grandfathering period during which you can renew based on the old pricing.

    How do I determine my cloud pricing tier?

    The cloud add-on tier is set automatically based on the maximum tier of the licensed JIRA applications on your instance. For example, if you have JIRA Software (50 users) and JIRA Service Desk (10 agents) on the same instance, your add-on tier is 50 users.

    Do you offer academic, community, or open-source licenses?

    For server add-ons, purchase and renewal is half-price if you have an academic license for your Atlassian host application. Server add-ons are always free for community and open-source licenses. Cloud add-ons do not have discounted or free licenses.

    For more details about qualifying for special licenses, see here.

    Can I extend my free trial?

    For cloud add-ons, you cannot extend your free evaluation period. All cloud add-ons are immediately subscribed by a user, and we provide a free evaluation period. This is a minimum of 30 days and ends on the second billing cycle after you first subscribe to the add-on.

    Mumo Systems provides support for this add-on.
