Newly laid turf with flattened patches

[rbuk33]

Hi, we had be turf laid approx 3 weeks ago. Ever since there has been almost constant rain so fairly certain the grass has had enough water, potentially too much? The ground does feel soggy j in certain areas.
In most cases, it's fine but there are seemingly random patches of flattened grass where it looks like someone has stood on it. It has barely been stood on in that time (except for taking some pics of it now - see a couple below!). These areas feel particularly wet.
Is there anything I need to be concerned if out will this sort itself out when the sun starts to come out?
Thanks in advance for any help or advice

Thanks for your reply. Yes on clay soil. They seemed to prepare the soil OK, removing old lawn, rotavating it and then using a roller on it, filling in any holes with more top soil before paying the turf. I just hope it does sort itself out!
Anything i should/can do in meantime to help it?

Thank you all for the advice and comments. I've brushed some of the patches to see if that helps, esp as rain meant to be less over next week or so. I've also bought some pre turfing fertiliser, as none went down beforehand, which apparently is fine for applying afterwards as long as watered in well

Hi all, looking for some further advice. Lawn now down 4 weeks with plenty of rain (as above!). 'm reading online now is probably good time to do the first mow, keeping height high using sharp blade etc. Do you think I should mow first and then fill the gaps immediately after, and if so with what type of soil? Top dressing or just get some lawn topsoil, either mixed with seed?
Or am I best filling the holes now with soil and seed, letting that area grow and then leave the mowing for a couple more weeks?
I'm thinking a mow as it'll create more space to see the gaps to fill in
Any thoughts appreciated, cheers

Thanks both. I'll try that over the weekend. Most of the areas haven't come back as yet. It does look pretty good in the other areas so hopefully seed with some top dressing will bring those areas back to life
