Keep Search Results After Redirecting from Account Creation to Sign In

[katska]

When attempting to create a new alert while not logged in to an account using an email address that is already registered, I was redirected to sign in. However, the search I performed prior to this redirection wasn't saved and I had to start again.
Usually Planning Alerts would automatically add the option to save the search as an alert when I sign in. However in this case I tried to create an account with an email address that already had account and somewhere along the way the search address was lost.

Context:
Whenever there is a search and then a sign in, I would expect a service to keep the search details or otherwise 'keep my place' in the journey and complete the task I began, in this case signing up for a new alert. In more straightfoward (search then sign in) circumstances Planning Alerts does this.

Steps to Reproduce:

• Be signed out of your account.
• Search for an address at https://www.planningalerts.org.au:
• Forget that you already have an account with an already registered email address, and try to create a new account with that email address -

Save alert
Attempt to Create a New Account:
Click on the "Create Account"
Enter an email address that is already associated with an existing account.
Proceed with the account creation process.
Redirect to Sign In:
Upon recognizing the existing email address, Planning Alerts flags the need to sign-in & redirects
Sign In:
Enter your existing account credentials to sign in.

Expected Behavior:
After signing in, I expect to see:

"Save this search as an email alert" flagged below the search address.

Actual Behavior:
After signing in:

Details of the search performed before the redirection are not shown.
No alert is offered based on the prior search.

So it looks like I cannot convert the previous search into an alert without performing the search again.

Impact:
This issue requires users to repeat their search after signing in to create alerts, leading to frustration and potential loss of engagement.
