Hi Andrew,
Maybe it can cause some issues, I noted I have:
Server Connection Collation set as utf8mb4_unicode_ci
Database > Tables > Columns are all set as utf8mb4_unicode_ci
I run Admin Tools > Change Database Collation > Custom: utf8mb4_unicode_ci
Why I have back Joomla > System Information > Database Connection Collation: utf8mb4_general_ci ?

It should be utf8mb4_unicode_ci, Am I right ?
Please, Am I missing anything ?
Please, Do you have any suggestions on How can I change it ?
