Hi, I recently created a new Google Cloud account to use the free trial credits and experiment with Google Cloud services. Shortly after creating the account, I think I accidentally upgraded/activated it as a paid billing account. From the Google Cloud documentation, I understand that upgrading to a paid billing account ends the free trial, but any unused welcome credit should remain available until the original 90-day expiration date. However, I can no longer see my remaining free credits in the billing area/reports, and I am worried that I may have lost them by mistake. I have checked the Google Cloud Console billing pages and reports, but I still cannot clearly find the remaining credit balance. Could you please clarify: 1. Where should I see the remaining free trial credit after upgrading to a paid billing account? 2. Is it possible to recover or confirm the unused free credits if they disappeared after an accidental upgrade? 3. Should I open a Cloud Billing Support case for this issue?…
