Thunderbird for android is failing to synchronise data with email servers.

Thunderbird for android is failing to synchronise data with email servers. Thunderbird for android is the exciting thing for people who prefer privacy and security as a default. But the transition from Top market email providers to thunderbird is not that smooth even after so much of testing the thunderbird android application still legs the reliability people look for a premium email client. The synchronisation with gmail and outlook servers is failing, it has to be manually synchronisation everyday or we don't get the latest emails. This is a headache for users whose work depends upon email communication and they look forward to Mozilla for a private and secure email client. Please I am a big supporter of open source and free internet but we need reliability for professional services. Please fix Regards A passionate User
