Monitors not showing in Uptime

I have an index with name "heartbeat-something". In the considerations for uptime it's said, that uptime requires an index pattern called "heartbeat-7*". https://www.elastic.co/guide/en/uptime/current/install-heartbeat.html
I've created an alias "heartbeat-7-something" as the workaround, but still uptime is not showing any data.
What have I missed ?

That should work. You can see where we define the pattern here: https://github.com/elastic/kibana/blob/7.4/x-pack/legacy/plugins/uptime/common/constants/index_names.ts#L8, in fact the 7 is not required.

I'm not quite sure what's missing. Have you checked the browser debugger when accessing the uptime app? I'm curious if something else is going on.

I had the chance to start from scratch removing all heartbeat indices before trying again, and it works, and without the 7 in the name. Don't know what the problem was before.
