Zen32 switch cannot be added

Purchased a C8 pro last week (updated to version 2.4.3.156 ) to replace my smart things hub. Before loading all 87 devices onto the Hubitat I first wanted to install the 4 each zooz zen32 multi button switch so I could control all of my scenes during network outages, unlike smart things, which leaves me having to go around the house, turning on each light individually.
Attempted to install the switch multiple ways, using manually installing, to using install by device type. Reading through the questions and answer streams, I attempted to use both Zen32 and Zen35 with no luck.
Quick note: I excluded all four devices from my Samsung hub, and ran an exclusion on habitat as well, then reset all switches to factory settings.
The only install that seemed like it wanted to work, was using my Cell Phone app to do a smart start enrollment. A couple of times I got two switches listed as pending enrollment. But they never enrolled, I waited a full day before we trying again.

I tried both secure and unsecured settings.
Attempted again with the new software version update (which I loaded today), and when I go to scan the QR code using smart start, the app abruptly shuts down.
I removed and reinstalled the app, and I’m still have the same issue with the app abruptly shutting down.


Please use the Diagnostics Tool to roll back to the previous version of the firmware. We identified an issue in 2.4.3.155-156 that causes the app to crash. It will be fixed in the next build.

I have five ZEN32 on a C8 Pro. All work fine and I didn't have any issue pairing them into the system.

2.4.3.158 is out with the fix. Please let me know if it works (or keeps breaking).

I have been setting up a new home for the last couple of months on a pair of C8 pros.
I have zen76s, zen77, and zen32s. I have noticed that the zen32s take longer to bootstrap and are overall more finicky to include.
