Yahoo/Apple Mail issue following update to iOS 16.1.1

Thanks @Dustin_R_308

Tried to contact Yahoo email support but they want me to sign up to a contract at £4.80 per month for 12 months before they'll talk to me.

They do have a FAQ on their help page but that's worse than useless and only seem to relate to Yahoo's own email app for iOS.

This problem only started with Apples iOS update to 16.1.1 so has to be something apple has changed.

Hi @Chris_D13 and many thanks for your help. I've now raised a support ticket with Apple and will update this thread accordingly as it progresses. It's certainly not something their first line support have come across and they've arranged for me to receive telephone support later this afternoon.

Update.

Apple support phoned as promised. Connected to my iPad and looked at what was happening but couldn't resolve. The first support lady then passed me on to next level support who tried a few things with no luck - ending with me not being able to reconnect to my Yahoo email account at all on the iPad. The second support lady ended up having me me factory rest my iPad with the promise that I wouldn't loose any data - which I did - but then she cut the call off!

So now I'm left with a factory reset iPad and no further assistance!

Now I've got to work out how to transfer all my settings from my iPhone to my iPad and then get all my data back.

If this is the level of support Apple offer then it is very disappointing!

This is very poor on Apple's part, very poor indeed!

Further Update

Now have almost everything back and looking like it did before the factory reset. The major exception is that one very important folder is missing in the Apple Mail App! Contacted sky who have moved their email offering to Yahoo and they arranged for Yahoo to restore everything that has been deleted from my account in the last 7 days. All of my 'sent' emails relative to that missing folder are now there, but all received messages relative to it - and the folder itself - are all missing!

The original problem is still happening in spite of the factory reset.

Contacted Apple Support Monday 28th. A very helpful lady, Anna, went through everything with me and discussed what the previous agent did. She has now escalated this to Apple's Engineers for a solution or a workaround.

She says will call me Wednesday 30th. I'll update this thread accordingly following that call.

I’ve now had quite a number of calls with various Apple Support people. Haven’t updated till now as there’s been no real progression.

However, yesterday we noticed that there was an iOS update to 16.1.2 released for iPhones. Following the update the Apple Mail app on both our iPhones seems to be working in the main, with only minor glitches. Talked to another Apple Support member yesterday and he advised that 16.1.2 will be released for iPAD soon.

Hopefully, that will be the solution. Watch this space.
