I’m in the same situation. I applied for my renewal passport after reporting my lost passport on 18th May. It’s been stuck on Identity details received ever since and it’ll be 7 weeks this week.
I managed to get on the web chat and whilst I told that my application is still waiting to be looked at they were able to tell me that I would need to submit a new passport photo. However, I cannot submit my new photo until they contact me. My advice would be if you can, try get on the web chat as you may be given the reason as to why your application is stuck where it is. It’ll say it’s busy the web chat but preserve. At least I know now and I have a new photo ready to upload. Just a waiting game as to when they’ll contact me asking for the new photo! Hope this helps anyone in similar situations.
