I downloaded MDL, and was planning on testing it on my upcoming trip through an airport listed as mDL-enabled TSA airport. As my (bad) luck would have it, on the morning of my flight, the first 30 days had just passed, and the wallet requested a refresh. Every time I tried to refresh, it gave me an error message. No dice on the test. This went on for weeks. I assumed it may have been a temporary problem, so I kept repeating my attempts. Always an error. I submitted a report, but never heard anything (although I did get a request to rate their “response” about a month later). I wasn’t able to get beyond that error, so at that point, I considered CADMVWallet to be unusable, at least for me. I deleted it and downloaded it again, and used it on another TSA adventure. This time it worked, though I’m dreading passing the 30 day mark and encountering that error once again. I’ll update this if the refresh works this time!
