Yeah. I knew that, too. To be clearer, I should have said something like “a Kirkland app or the ReSound Smart 3D app from the Apple Store.” I’ve never patronized Costco for HA’s so I have no good overall idea what goes with apps and HA’s from Costco.
I forget whether it’s been mentioned recently in this thread but the typical ReSound recipe for poor app connectivity is something like unpair your HA’s, uninstall the app, (reboot your phone?), repair your HA’s, reinstall the app. If one hasn’t tried that yet, it might help.
ReSound promised snappier and better connectivity in the latest version of the Smart 3D app and I’ve found that to be so relative to past iOS versions and past Smart 3D app versions, some of which have worked relatively lousy together.
Edit_Update: for clarity in my previous post, I’ve inserted the word “ReSound” as indicated in the phrase quoted here, using bold italics to indicate the insertion.
Do the Prezias use Costco’s proprietary version of the Smart 3D app or can you use the ReSound Smart 3D app straight from the Apple Store?
Further_Update: More intermediate steps to fix connectivity problems than repairing HA’s and reinstalling the Smart 3D app are, first, just force-closing the Smart 3D app by swiping up towards the top of the screen, then relaunching from its Home Screen icon. If that doesn’t work, rebooting one’s iPhone can sometimes fix things, too. I don’t think there is a single culprit to be blamed. There are probably bugs in both the Smart 3D app and in iOS causing problems from time to time but as I’ve mentioned above, the latest version of the Smart 3D app and iOS 15.5 usually work well for me with Quattros.
