Similar experience here. Walmart is also terrible at this. Amazon Fresh/Prime Now is reliable 90% of the time. But I've had them cancel deliveries just 1 hour before scheduled time once. Would never trust any of these services for any important items. Not to mention the ridiculous markup on some items.
This is depressing. Trello is a beloved software for a lot of people. It's sad that Trello decided to sell off to Atlassian. I can't believe the same company that makes Jira is going to run Trello. SourceTree is the only software that they make that doesn't suck.
