Saved messages not appearing in second device

I am afraid that some messages are getting miss since 2.43.0 **(desktop core is 2.43.0 but android is 2.44.0**), I noticed this first in https://github.com/chatmail/core/issues/7952 where I focused on the channel problem but as I said there, there were another account without channel where normal messages were not appearing in both devices

now it happened in the same account where I have the channel:

I saved some messages (some are videos but other are simple text messages) in android and they are nowhere to be found in desktop:

in Desktop nothing of this appears, even if the messages themselves are in the original chat, so it was the sync-messages that got lost somehow maybe while syncing after being offline the sync messages got somehow processed before the actual messages. If I now try to save some of that messages again while both devices are online, it works, here you can see desktop's saved messages after I saved a message again just now:
