Anyone else who can't file their vat return to HMRC?

Hello, johnjeltham.

I’ve checked some updates and was not able to see any reports similar to your issue. Let’s try to check if this has something to do with your browser by filing the return through a private window. Here’s how:

• For Chrome, press Ctrl + Shift + N.
• For Internet Explorer or Firefox, press Ctrl + Shift + P.
• For Safari, hold down Command + Shift + N.

If it works fine, you can clear your browser’s cache or use a different one. Overloaded files stored in your browser can sometimes cause issues like this. 

Please let me know if the issue continues. Any further details like error messages or screenshots would be very helpful.
