Kaitu - Network Accelerator

This update focuses on bug fixes. Upgrading is recommended for all users: • Fixed membership expiry date not refreshing right after a successful in-app purchase • Fixed the status indicator still showing "Connected" after the connection had dropped • Fixed renewals after expiry being back-dated — your new period now starts from the payment time • Fixed brief service interruption while a payment retry was in progress • Fixed sign-up incorrectly reporting "invalid parameter" when the email was already registered • Fixed several layout issues on smaller screens Other improvements: • Smart server selection can now exclude countries/regions you don't want to use • Refreshed interface colors with clearer visual hierarchy • Improved connection stability and success rate
