Has Kindle made any changes recently I am not aware of?

[SHDB]

Have been using Kindle on my iPhone for years now. iPhone 7.  Always took the mobi, then later, ePub files and emailed them to a Kindle account. Would open Kindle on my iphone and the books would download.

Several times over the past 6 weeks they wont upload into my account and back onto my phone.
Seems my account has wiped out most of the books I had there and wont upload new ones.

For the record files have just been simple murder mysteries, romance novels and dog books.

Just tried 2 new books and again, they will not upload. Both were ePub which is what my kindle was accepting as of about a year ago. Before that only mobi.



This is the message I have received to both books just now.

Late reply. If it helps.

The email client or the service perhaps removed the attachment. Hence the error.

Relevant Update:

Note: Beginning in late 2022, you'll no longer be able to send MOBI (.AZW, .MOBI) files to your Kindle library using Send to Kindle. This change won't affect any MOBI files already in your Kindle library. You can still read them with Kindle. MOBI is an older file format and won't support the newest Kindle features for documents.
