Woocommerce-ios: Log in flow: Choosing "Try another account" shows spinner forever

[eshurakov]

Describe the bug
Choosing "Try another account" on the last step of log in flow completely blocks the app. The app can be used again only after force restarting it.

To Reproduce
Steps to reproduce the behavior:

1. Request on magic link and tap on it in the email
2. Tap "Try another account"
3. See "white" screen and a spinner. The app is now stuck on this screen

Screenshots

Expected behavior
Restart the log in flow

Isolating the problem (mark completed items with an [x]):

• [ ] I have deactivated other plugins and confirmed this bug occurs when only WooCommerce plugin is active.
• [ ] This bug happens with a default WordPress theme active, or Storefront.
• [x] I can reproduce this bug consistently using the steps above.

Mobile Environment
Please include:

• Device: iPhone and iPad
• iOS version: 14.2
• WooCommerce iOS version: 5.6

@ctarda Is this something that will be fixed with the UL project?

[ctarda]

@shiki not per se. I think we should fix this independently from UL

Thanks for this report! I missed it and opened a duplicate in https://github.com/woocommerce/woocommerce-ios/issues/3367, but I'm going to go ahead and close this issue since the other one already has notes from researching the cause.
