Hello,
i made (maybe) last week a mistake with a update on several CAP XL ac Acesspoints with the wrong Router OS. I guess i renamed (by mistake) the arm64 to arm and was updating several Accesspoints. They are running on 7.12 but we had a lot of issues that week.
We are using a CCR2004 with CAPsMEN. I wan’t to make sure that a correct 32bit version will be installed (by normal update function). With 7.11.2 we didnt have any issues - but i am not sure how i can downgrade the accesspoints - via packages?
Feeling relly like fool but I hope someone can help me 
Regards, Johannes
