I am using Oracle's services for about 17 days now.
The first thing I did was to create a 4 OCPU, 24GB RAM, ARM Instance. Until now, I had no doubt I'm within the Always Free tier's limits, however, today I also created an AMD instance and noticed an "Always Free" badge next to the AMD Instance's name.
Now I am wondering if my ARM Instance actually wasn't within the Always Free tier's limits since it's missing that badge. but on the other hand, I also haven't used any of the free credit that was granted to me, which indicates that it is within the Always Free tier's limits.
Please let me know if I need to do anything to be able to use the ARM Instance from the Always Free tier or if I am already and don't need to have that badge next to the instance name.
