Fix fish app issue

[KristinaRiemer]

Task to do
Get location points to show up on the map on the Explore tab

Reason
The points aren't showing up, might be something to do with needing to use new reframe function in dplyr as per this warning message:

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.
