Ah ok, @Mike, you’ve beaten me to it!
At this stage i’d have just recommended a double check with DWP to make sure they had your form, as I couldn’t see a post saying you’d had a confirmation text, or letter acknowledging receipt of your forms. At least you know they have them. Having read around the disability forums, there does appear to be some delays in some areas with the process, so maybe you’re just in one of those areas.
Hopefully it won’t be too long before you hear something.
