This weekend, the issue seems to have mostly resolved. The error is appearing less frequently now, and when it does the "Retry" button actually seems to do something.
There has not been any updates or announcements from TNT in the app or elsewhere, so we're not sure what may have changed, or if there might be any form of recompense for those who missed out on the Tia's Seasonal Exchange event as a result of the glitches.
