Need help with the Joplin Features

I want to ask, I wish someone could help me.

I’m not getting complete synchronisation; it’s missing notes that should be there, like in my old directory. I got newly created notes that are not being synchronized to mobile, so I am not sure if they are being saved correctly. I need a way to verify that. Also, one of the main things I’m having trouble with is these screenshots: there are a lot of downloads that can’t be downloaded. What is wrong with this? I got this from the app on GitHub that downloaded all the data from OneNote to MD markup files, and it should’ve imported everything, including the images, but it did not.
Do you have any paid support options to help you with these questions?

Maybe ask this in the Support category?

@FransLumbs I'm also closing this - the reason is that I can't simply move it because what's missing is all the information we need from the support template. So for support requests, please use the support category.
