Ads while being an ultimate fan

To start, this is only on mobile for some reason, yes I'm signed into the same account, and it is skippable. This started a couple months back no more then 3 I believe. For some reason on mobile I'll get 1 ad that is skippable. I don't really care since I can skip it but still find it weird that I'm getting ads while being an ultimate fan. Im not sure if something has changed but I know I'm an ultimate fan and I know Im not behind on paying either, since apparently if your late you'll start to get ads but are still considered an ultimate fan. Again I'm not mad or upset just find it weird. Lmk if I'm dumb or not.
