I haven't had that issue, although I mostly run Orion on older systems since the support is excellent on older macOS as well. Were you using extensions?

I use both kagi and Orion, both on mobile and Mac, and I have to say that there a few bugs. On the other hand, paying for a software and a service feels good.

My only real complain with Orion is that it's not open source. I get the rationale behind, but still I don't like it.
