I loved the “flower fields magic” screensaver which has suddenly disappeared and the default screensaver was selected in its place. Why was it removed? It was beautiful.
I don't see anything in the Channel Store called "Flower fields magic screensaver", but there are plenty of flower screensavers:

If you try to ask Roku why something was removed you'll get the standard response:
Why is a channel no longer available on my Roku® streaming device? | Official Roku Support
Dear valued user,
We hope this message finds you well. Unfortunately Roku has disabled all of our screensavers, and we are currently working to restore them. We understand that our audience, which comprises around 2 million users, relies on and enjoys our applications. We appreciate your patience and attention to this matter.
Over the past three years, we have been committed to maintaining our screensavers and adding new features such as a Clock, Crypto market price, and Weather updates. Our screensavers have been freely available to all users, with the exception of our Weather widget, which requires an additional fee for access to weather data. We are proud to say that our screensavers are beloved among Roku users, and we are grateful for the positive ratings and feedback that inspire us to keep improving.
Unfortunately, we do not have the ability to manage disabled applications. If you have any subscriptions, we encourage you to reach out to Roku for a refund. We want to reassure you that we are doing everything in our power to restore our applications as soon as possible. Any new information will be posted on our website at okkocorp.com
Once again, we apologize for any inconvenience this may have caused, and we appreciate your continued support.
Best regards,
The OkkoCorp Team
Perhaps this is in reaction to the many complaints seen in these forums that the purchase of OKKO's $10 Weather widget only applies to the particular "free" OKKO screensaver for which it was purchased.
