Problem: Outgoing MMS messages are blocked while Adguard is active; haven't confirmed whether inbound works. Behaves the same regardless of filtering mode (VPN or Local HTTP Proxy). Once Adguard is disabled MMS messages go out normally. Tried adding Verizon MMS URL to whitelist...didn't help (didn't think it would but worth a shot). Obviously a problem as enabling/disabling Adguard is not a realistic option.
