Investigating
Some customers might experience problems connecting to SMS SMPP endpoints over TLS due to a change of certificates.
The change has been reverted. If you observe any issues, please restore your configuration to what was previously working on May 22nd or earlier.
We will update with definitive instructions as soon as possible.
