No longer syncs

Have been using E-Wallet for years. Now no longer syncs after upgrading to iPhone 7. Initially received a quick response from vendor, but after I let them know that their initial suggestions didnt help, --nothing. Complete radio silence on their part. Would love to see this get corrected, or at least receive an acknowledgment that they are researching the problem.
