Although logged in, I cannot upload any astrophotos within my account. After selecting “upload your astrophotos”, I am taken to a page with a small rectangle, like a file symbol, with a bird in it lying on its back.
I am using a desktop with a Linux OS (Ubuntu type).
This was fixed in version 250422.1658. Please check if you have an upgrade available at the very bottom right of the page, under the copyright notice, and let me know if it works for you in version 250422.1658
Aha! The page has now upgraded to 250422.1705 and yes, the facility to upload is there! Many thanks for finding that for me.
Great, thanks for letting me know! 
Clear skies!
