SharePoint newbie here. I have created an out-of-the-box list (with no custom code) and have been happily using it. This morning when I went to create my 16th list entry, it would not allow me to save the attachment (everything else in the entry saves, just not the attachment).
It allows me to upload the attachment and hit "save." However, when I open the entry, the attachment is gone/never actually saved. This is true for both new and existing list entries.
I restarted the browser, tried different browsers, restarted my machine, tried different types of attachments, etc. I checked the list settings - attachments are enabled.
I am having the same issue as this question but with the exception that my list has no customization.
Appreciate any help!
