App keeps crashing on my iPhone – Frontier Airlines Review

After several years of good use, the Frontier app keeps crashing on my iPhone (January 2022). The rebooted my phone. I deleted and reinstalled the app. Still crashing! I put in the info for booking a new flight and hit the search button. That’s when the apps closes unexpectedly. This is a big problem. Please fix.
