Infuse cannot see qnap shares

I’ve recently noticed that my infuse phone app cannot see my qnap shares any longer. This worked well previously. I’ve checked all posted recommendations and possible config options but no luck.

One of the responses to a post asked if the disks had been upgraded/replaced which is in fact one of the recent changes to my qnap setup. Is there a specific action I need to take to address this potential disk-related issue?

Any help would be appreciated.
