I have tried that, it will disable autoscaling (not something I want). Trying once again:
❯ fly scale count 4 --max-per-region 1
Warning: Autoscaling is now disabled for <app-id>
Count changed to 4
❯ flyctl releases list
VERSION STABLE TYPE STATUS DESCRIPTION USER DATE
v89 false scale failed Scale VM count: ["app, 4"] 3s ago
v88 true scale in_progress Update autoscaling config 1h47m ago
As you can see, status is shown as “failed”.
And flyctl status is now missing the “Deployment status” table, instances are still at v88 and at same region.
