Flightvew App Stopped working (in 30 day trial)

Tried to cycle FV app (recently loaded for 30 day trial) on and off several times (on my personal Ipad) to clear a lock up of the EMS data (red x’s) showing on the split screen (i.e. where map displays); Map data was no longer selectable. Issue remained after on/off cycles so deleted app and tried to download again on App Store but unable. Is there a remedy to get the app loaded again (during a trial period where it’s been deleted)? Tried to send a trouble ticket; would not process on the FV website. Thanks.

Update; the Flightview App (30 day trial) successfully loaded (again) to my Ipad today and seems to have correct functionality.
