some messages appearing in triplicate

[simonmichael]

Beginning today, several messages I have posted appeared in triplicate (two extra copies). Other users have noticed and are inclined to grumble, so I'd welcome any pointers to help diagnose/prevent this. Nobody else seems to be talking about it in the matrix/element rooms.

• I use a matrix.org account

• One of the repeated messages was posted in #lambdahack:mozilla.org, with Element IOS

• The other was posted in #freenode_#plaintextaccounting:matrix.org, with Element desktop (mac).

Usually I see a single copy of my messages, as expected.

Logs being sent: yes

• Element macos 1.7.4
• Element IOS 1.0.0 rebranding #20200713192130

This appears to be a server-side issue, likely https://github.com/matrix-org/synapse/issues/3365

Thanks.

Maybe @reivilibre will make progress on this soon. If not, might an interim workaround in the client be possible ? Eg, wait longer before retrying, or ask the user before retrying (maybe it does this ? If so I have a solution: be more cautious/wait longer before clicking "resend").
