Can’t read custom info customer types in boxes

Latest version of WordPress, WooCommerce, this plugin, and Storefront theme. On Jan 20, after over a year, stopped being able to read any custom info that customers typed into custom text boxes. Up to that point, I was using the Twenty Sixteen theme. Contacted Phoeniixx support and followed all recommendations. Gave up. Started working on it again early this morning. Double checked all updates, re-installed the Phoeniixx plug in, changed theme from Twenty Sixteen to Storefront, and tested using two listings, and re-creations of those two listings. On about 50 attempts, only twice did the custom text info show up on the completed fake order. I don’t know what else to try without getting into areas that I have no clue how to navigate. I have stared at this so long that I know I am not able to see the problem that someone else may be able to with fresh eyes. I sent another email to Phoeniixx today, but have not heard back. PLEASE help me. Lisa
