I agree that the releases seem to be getting less stable, not more. Looking forward to beta 4 though.I expect to see more time between bega releases as the OS gets more and more stable.
Unfortunately, we are far from that scenario has we I these lines, beta 3 has been the most unstable for me on almost all aspects (iPadOS and iOS). This has me worried that not enough feedback is being given or someone is sleeping at the wheels at Apple Park.
Late release maybe? Fingers crossed
