I have iOS, and use MacBook/Linux.
EDIT: Wow! It’s impressive how many different ways there are to achieve this. I tried obsidian git, but couldn’t get it to work as expected. Remotely Save is working perfect! Obsidian flew under my radar all these days because I thought sync was the only way. I’m looking into plugins and there’s literally a thousand plugins. It’s kinda overwhelming tbh. I’ll make another post for plug-in recommendations and workflow setup advice. Thank you all!
Do you do much editing on your Windows machine? I tried using iCloud sync but found that the documents would randomly undo a sentence or two as I typed. Also had problems with Windows sometimes not uploading whole files.
