Shib IdP: Box app failing on iOS 13

We're getting reports of people not being able to log into the Box
application from iOS/iPadOS 13. One screen shot I've seen has the IdP
error of "NoSuchFlowExecutionException".

Box support pointed us to new TLS certificate requirements at

but our cert and its CA pass by my reckoning. That page also says Safari
on iOS13 would fail, and I've had someone tried a protected website from
Safari and that works.

We're running IdP 3.4.3 on tomcat 8. Any ideas? (SameSite maybe?)
