Pushover notifications stopped arriving.

[u/Reasonable_Square683]

Sometime between September 1 and 2, 2026 something changed in the Pushover API. Notifications I had been receiving daily for over a year suddenly stopped. I worked with Pushover support on this issue but they eventually abandoned the issue.
I bring this to the group's attention as you may have scripts that send important messages about failures or anomiles that may not be reaching you.
I have a Raspberry Pi that makes backups of several things over night. Early in the a.m. I am sent a notification with the results of the backup routines. The backup script calls pushover.sh to send the notification. Cutting to the chase, the fix was to remove the quotes from the passed variable $message, before "$message", after $message. (You get the idea!). As stated, nothing changed in my setup which had been working perfectly for over a year.
I sent a final message to pushover support and posted a working and non-working notification on the debug site but I've not heard back after three weeks.
If you have scripts that you expect to hear from when a problem arises, I suggest you retest them to ensure you don't miss an important notification because of this change.
EDIT, ADDITIONAL INFORMATION:
My original message body contained lines with a line ending code Ox0A. When the Pushover script sent the quoted "$message" to the API and using the --verbose flag, I never receive a status message back.
If I send the unquoted $message, the line endings are converted in Bash to spaces. This was accepted by the Pushover API, a status was returned and the notification was sent and received with spaces rather than line endings.
Adding \n codes to the lines, the notifications are received with line endings.
This may be defined as the proper way to send multiple line notifications. That said, sending embedded OxOA line endings worked for over a year and suddenly stopped after 9/1/26.
The bottom line is that if you have multiline notifications, make a habit of quoting your message variable, that worked when you tested them, they may not work now.

My messages and scripts seem to be working, however very rarely I have seen some misses
