My Question or Issue

I've noticed that the duration of adverts are now longer and rather than 1 every 30minutes or so (haven't timed the time period between adverts but it doesn't feel like that has changed) there are now 2 adverts back to back. Has anyone else noticed this? 

Totally understand the need for adverts on the free version but to double in time and duration is a bit rich.
