I'm using V3.8.3. The built in one,I assume it uses the browswers spell checker is what you're referring to, will flag and underline in red but how do you get the suggestions on how to correct it as right or left clicking does nothing. I'd prefer to use the built in one. A spell checker should be integrated and native from the very beginning on a application whom sole purpose is to write documentation. I've tried on chrome and brave.

On the syspell side I'm not sure if the plugin crashes or not but if I resolve one mispelling and move to the next one and right click the plugin does not show up. I have to click a few time and then it will show up in the list on a right click. Also, with the preview "apply corrections" it's the only way it will fix the mispelling when choosing one; without this enabled you can click on the correct spelling but it does nothing.

I can try to help but I need to know wich console logs you need from the browser, a snipit of when I try to do engage the plugin and it doesn't show up?

I have to use a docker version since I need my documentation regardless of what computer I'm on.

Is there a better forum for English users? I don't even see Siyuan on reddit much which is a shame because it has a lot of potential since it has features that docmost and trilium have in one system and those two are some of the more popular ones. Is Siyuan considerd mature at this time?

Thanks for your reply.
