Are you experiencing performance issues with Gryzzly? Is the application slow to load, or are you having trouble submitting time entries? This guide will help you troubleshoot these problems.

Gryzzly uses HTTP/3 (QUIC), a modern web protocol designed to improve speed and security. However, some antivirus and firewall software may incorrectly block this protocol, causing connection issues.
