Guest services had me uninstall and reinstall again, which didn't help. They did help me log in to the Navigator web page, which works, it's just clunkier than the app (when working!) My phone is a Samsung S23, so it's relatively new. How would I clear the cache? I've reinstalled multiple times now, and tried while in Ketchikan in case it didn't like the ship ifi, but I'm still getting the same white screen. At least hubby's app still works.
