Warning: Returning more (or less) than 1 row per `summarise()` group was deprecated in
dplyr 1.1.0.
ℹ Please use `reframe()` instead.
ℹ When switching from `summarise()` to `reframe()`, remember that `reframe()`
  always returns an ungrouped data frame and adjust accordingly.
ℹ The deprecated feature was likely used in the ssimparser package.
  Please report the issue to the authors.
`summarise()` has grouped output by 'format(flight.flight_date, "%Y-%m")'. You
can override using the `.groups` argument.
