My android app is very slow on fiber to access one server, but not on 4G and never for another server.
Steps to reproduce
Latest normal or beta app
Server with slow connection is Mattermost.adaptationradicale.org
Summary says it all I think.
Only the server mentioned and only at home through wi-fi/fiber connection do I have this slowness. Not through 4G and never with other server (eg FramaTeam.org)
Connection, message sending, updating… Everything is slow with the app. Like nearly 10 seconds to update.
No slowness through web, though.
