E-Credits not showing in account, and not linked to SkyMiles #.

I made changes to a couple different flights recently, which resulted in e-credits. I went to book another flight today, hoping to use those credits, and realized they are not in my wallet. I found the emails and entered the numbers, but doing so removed my SkyMiles # from the booking and won’t let me add it back in. Preferred seats cost money, which should be free with my platinum status. Same thing is happening for my partner.

Chat is saying this is because the flights were booked using some credits, so these new ones are ‘reissued’, and they can’t tie a SkyMiles number to reissued credits. They were able to book the flight for me over chat and apply them.

My app also gives me an error message when I open my vouchers tab and I can’t see any vouchers that are showing online (RUCs, comp. fare, etc…)

Anyone else having this issue? Credits always used to show in my wallet right away. Seems they are making it more difficult to redeem e-credits.
