Hopefully ILFORD / Harman will be able to make a further statement at some stage when they believe these problems are more fully understood.
You overlook that Ilford already has reacted last June. Basically saying:
-) that these cases are utmost rare
-) only show up with films having backing paper
-) that there is no link to a whole batch of paper
-) that they assume it to be related to the coating of that paper
-) that they further assume that variations of that coating plus special conditions on the user side are triggers
These user-side conditions they assume each on its own
-) storing/handling other than advised
-) extreme long exposures
-) using a prebath
-) using Pyro
Nor have I ever found Pan F to be prone to fade if not processed immediately or within a few days.
A few days don't matter, but if you wait long enough, Pan-F absolutely does have latent image fading. It is not at all tolerant of neglectful delays prior to processing. (It does seem to preserve the latent image decently well if frozen while stored, though.)
The examples you have uploaded seem strange that these are from only one person. If they were bad all over then there would be an uproar. I think it is down to operator error.
A few days, a week, or a month I have never ever found fading a problem. About 6 years ago I lost a part exposed 35mm film after I removed it to replace the slow film with HP5+. It apparently dropped out of my camera bag and didn't realise it has gone until I got home. I thought it must have dropped out onto the ground so accepted I had lost it. 5 weeks later my partner found it on the garage floor. How it got there I have no idea, but when developed, it was perfectly normal. Perhaps because I always expose Pan F at 40iso instead of 50 and reduce the development in ID11 by 10% that makes the difference, I don't know.
I had a roll fade so badly that the edge markings disappeared - all I could see was the fogging on the leader, and some very vague evidence that at least some of the frames had been exposed. Most were simply transparent.
Ilford responded to me within a few days and replaced the film (HP5+) soon after. There is a form to fill out on their website.I'm waiting for feedback from Ilford, have the spots problem on several Delta 400.
Looking into previous posts, someone reported directly to Ilford in February (2020) and got the reply in July. Is this the normal leadtime?...
Thanks! I had already filled the form but got no news, not even an email confirming reception. By coincidence got it today and it is now sorted.Ilford responded to me within a few days and replaced the film (HP5+) soon after. There is a form to fill out on their website.
Was this 120 film? The infamous backing paper related mottling?I have just developed two Delta 100 films with Atomal 49. Both film have heavy mottling. Print on the box is

I know they are beyond the recommended time. But 100 ASA film should be usable even 10 years after buying it.
I doubt that. The mottling issue was happening films that had not expired. And it doesn't do well for Ilford's brand image to have issues with any film, even though they have no responsibility for the film after the expiration date.Maybe manufacturers found the way to steer us away from using expired films???![]()
For information Ilford now state as soon as possible but in any case withing 3 months for the processing of Pan F after exposure in camera

Yes - Pan F is unusual that way.Is this true for 35mm as well?
Yes - Pan F is unusual that way.
Then I am going to have to quickly finish the roll and send it out for development since it doesn't work well with monobaths.
?
I shot a few rolls of it and developed it in DF96 without issues.
