The error looked like this. [onlyoffice-presentation.log](https://github.com/aleho/onlyoffice-ce-docker-license/files/6755759/onlyoffice-presentation.log)

When I checked, the spreadsheet and document worked fine, but the presentation did not.  I'll be happy if this is fixed in the future.

Looks like it's a lot harder than I imagined...

Thanks for the reply! I'm sorry I'm not communicating well. Normally, you have to scroll down and load the image to start getting thumbnails. Since this doesn't allow for smooth...

I'm using the grid view.

So running an app in the background causes so many problems... I used the Preview Generator to create a preview first, and it was faster than before.
