I have set the retention policy on my Thunderbird account for 30 days both in the setting for the inbox and the All Mail inbox and I have used the same setting for my account however it only works on the inbox and I have 1745 message in the All Mail folder which intermittently deletes the older messages and then restores them.

Am I doing something wrong?

I have posted up to yesterday requests for help with Thunderbird to both mail.gmail.com and to Thunderbird. Part was solved by gmail but they said that for slowness to contact Thunderbird. I got a notice things were solved and this morning both the pop.gmail.com (downloading posts with Thunderbird) and the smtp.gmail.com (sending posts with Thunderbird) were fast as usual - few seconds. I sent about 35 posts and only the first took two second. This evening the sending posts from my Thunder bird (of the desktop computers - 10 posts during an hour) take about two minutes. Sending from the smartphone take a second.
