If you delete resources you should be able to reuse them in free tier? A warning

Summary: Problems:

• If you delete resources you should be able to reuse them in free tier? If no OCI resources were available before you delete them, what resources you delete you can't get back. You have know way of knowing if this is going to happen.
• Pop-up error messages need to be displayed long enough for people to read them.
• Also this video from Oracle Learning is interesting as its title doesn't match its content, no mention of how to restore. Block Volume Level 100 - Part 4: Backup and Restoration

Content: I decided to do some house keeping and delete current instance and backups.The plan was to do a complete clean out and refresh what was there before.
