I think I found a bug in Mastodon, instance is running 3.5.0.
when suspending a user along with a preset suspension reason message, the email doesn't get sent and the UserMailer#warning Sidekiq job fails with a error that looks like this:
"ActionView::Template::Error: undefined method `linkify' for #<ActionView::Base:0x00000003495a40> Did you mean? link_to_if"
@packetcat just noticed https://github.com/mastodon/mastodon/issues/17481 btw; this is probably relevant to your post
@aescling hm not entirely sure that one is relevant
I opened a new bug issue
