is the server very slow today

Hey Vitaly, thanks for reporting. I checked with the team, and it looks like our servers are doing fine. I was also able to upload a PDF on my end with no issues.

When you say you are running into issues uploading, what happens? Does it just take a long time to upload the PDF, or does it not upload at all? If it's not uploading at all, could you send the PDF to support@zztakeoff.com so we can check on our end?

it just thinks for very long time and dont do anything

Gotcha. Are you available to jump on a Zoom call so we can see what's going on? You can reach out via our website chat or support@zztakeoff.com, and we can jump on a Zoom call.
