SmartAdvocate Attachments Restored, Public Signing Pages Back, Faster Mobile Chat

A maintenance release on top of Portal 2026.5.0, with patches for a few regressions that surfaced over the past few days.

• portal Public signature request pages load reliably again: clients opening signing links from SMS were intermittently hitting an error page after the last release. Fixed.
• portal SmartAdvocate message attachments reach the case file again: a recent regression was silently dropping uploads. The message looked sent but the file never landed in the CMS. Fixed, with retry coverage so any attachments that dropped in the gap will reattempt automatically.
• portalapp Mobile chat members panel loads instantly: was timing out on the largest firms. Now opens immediately for everyone, and co-clients no longer leak into the staff list.
• portal CaseChat opens cleanly on first load: no more error overlay on first sign-in.
• portal Inactive firms no longer queue stale CMS sync work: the deactivation lockdown now covers messages and chat alongside documents.
• portal Re-saving CMS credentials on integrations settings no longer fails: a long-standing error when rotating an existing connection's credentials. New connections were always fine.
• portal Subscription descriptions wrap inside their cells on integrations settings: no more overflow under the toggle column, plus tightened copy on the most common webhooks.
