Sales and Trends filter broken (Parent App)

For a long time we've been seeing an issue with the Parent App filter in the Sales and Trends report with specific user accounts when accessing a specific developer storefront. When we would try to filter, it would throw an error saying:
"An unexpected error occured. Try reloading the page. If the problem persists, contact us"
We opened a ticket and have been waiting for months for any information.

Anyway, today it seems to have spread to all accounts on all storefronts. Is anyone out there able to use the Parent App filter right now?
