I had the exact same experience and switched from Tauri 2.0 to Electron after a month.
No only were there UI inconsistencies, but Safari lags behind chrome with things like the Popover API and the build/codesign/CD ecosystem for Tauri is incredibly scattered.
When I was using it, IAPs were still not really an option for Tauri or at least I could not find any docs or resources about it.
Same here. We went with Electron mainly for consistency and stability. The larger bundle size wasn’t an issue for our particular project, so the decision was pretty straightforward.
