The Notification Icons plugin will become even more useful: expect a beta release early next week
The new Oppo watches are the very first with rectangular screens. I am working on version 9.84 which will support the new form factor. Expect the first beta within a week. Thank you for your patience!
Update (9/29/2020) The first beta of v9.84.1 was submitted to Google for approval. It should be available to beta testers very soon!
