Thank you for your answer.
I saw it just when I managed to reproduced this bug with debug log enabled... but it seems that debug log is useless in the end...
The problem is that this issue happens daily for me... and I missed some important mails because of this. I think I never had this this issue with other mail app before (I mainly use the stock app on Samsung phones), with the very same mail account @Yahoo.
The strange thing is that this issue happens in the following manner (I did some more investigation since my first post) :
- checking mails -> new mails are present -> they are downloaded and are correctly marked as UNREAD.
Then, some minutes or hours later:
- new mail check -> new mails are present -> they are downloaded but the previous unread mails are then marked as READ.
So, at a point, the mails were correctly seen as UNREAD by AquaMail.
The other problem is that, when I only use my web browser to read my mail (phone is off), I never had this issue. When my phone (and so AquaMail) is on, the new mails are marked READ in AquaMail and also on my web browser. (you already said that).
Last : when I manually mark a message as UNREAD, it
seems to be protected against this issue*.
Would you like me to send you my debug log anyway ?
Thanks again,
Nicolas
* would it be a way to find a work-around, by allowing AquaMail to automatically mark a new unread mail as READ then UNREAD (it may "force" this state for the new messages) ?
