@ValentinePomMom
Thank you for your post! I understand that your OTA antenna favorites list has been erased, and I would like to assist you with this issue.
First, could you please let us know which Roku TV model you have? Additionally, could you provide the serial number and the latest OS version on your Roku TV? You can find this information by going to Settings > System > About.
I look forward to helping you further!
Best,
The Roku Community Team
