It was the same way on the old version. You just have to wait. My last mix of multiple UTXOs took about 3 weeks to fully mix. The longer the timeframe, the harder it is to run analytics on it.

I swear I'm the older Sparrow versions when you hovered, it would show it was registered as an input out of the total inputs in the pool and then show more progress on the progress bar after it joined a mix
This almost seems like it's stuck and hasn't registered
Oh well 🤞🏻 it finally joins a mix
You might be right. I can’t remember if there was a percentage when you hovered over it, but there was definitely an advance on the bar. I think you should be fine. You can always pause and restart the mix.
