Struggling with slow or stuck document loading on Collabora Office for Android? You’re not alone and we’ve got great news! 
We tracked down a sneaky issue where Android’s WebView loadUrl would choke on large strings (looking at you, base64 tiles 
). Our awesome dev Skyler dove in, did some serious detective work 
, and built a slick new WebSocket-based workaround that blazes through document loading.
The difference? Night and day.
This fix is now live in Collabora Office 25.04.2 for Android — grab it from the Play Store and enjoy documents that load like a dream.
