Send only YE1+RootYE intermediates, skip cross-signed ISRG Root X2
iOS 14+ and Android 11+ have ISRG Root X2 in their trust store.
Sending the cross-signed ISRG Root X2 alongside the trusted
self-signed version can confuse the cert path-building algorithm.
Chain: leaf -> YE1 -> Root YE -> [ISRG Root X2 from trust store]
