I have tested the new version and first of all, thanks Sergey for your work and the time you spend on it, both for improvements and for user ideas.
I have tried with the php version 8.2 and the truth is that it goes a little faster.
However, we continue to have issues with opening .pdf files on both iOS and Android devices. In Android, for example, it tries to load the Google PDF file viewer plugin, but it doesn't show a preview and when trying to open it with an installed app, it fails to load the file.
On iOS, it still loads the viewer using jQuery, with no apparent change and not in a new tab as I had expected. I think I'll go back to the old version and move all the files to .docx.
