Constant Timeout while "Entering World"

Attempting to use the WoW Companion app, connection times out on “Entering World” everytime, without exception.

Samsung S20FE, fully updated, attempted with Wifi and Data

App updated, uninstalled, reinstalled. Connected to other regions besides NA and back again as instructed.

I followed every suggestion on the Support article, but the connection still times out at “Entering World”. Any other suggestions?
