I ran into the "Unexpected Error" problem trying to combine UR points from my Ink business account to my CSR account. I tried removing all known card links without success. I called Chase and the rep tried to tell me it was a browser problem. I told the rep I tried it on 3 different browsers and still had the problem. The rep concluded I should simply call in when I want to combine points. I requested to talk to a supervisor and he promised to escalate this issue and said a tech team will contact me within a few days. Having worked in the computer industry for 35 years, I know some activities are relegated to overnight batch processing. The next morning I tried again and it worked. So if you run into this problem, I suggest removing all card links and try again the next day.
