Hello everyone I would like you to help me if possible, I comment the problem I have with Thunderbird on Android and is as follows, as I can put a sound to send a message and if you can not, how you can see that the message has been sent correctly. I thank all the developers because you are doing a good job with Thunderbird for Android and people like me who have been waiting for years I think from my point of view that there are some things to improve to be almost perfect .... Congratulations for the great work and effort you are doing every day to make Thunderbird better, greetings and a big hug to all of you.
