I asked them elsewhere in the thread and Connect doesn’t have crossposting either, fwiw. I have no idea why they’re posting in this thread, their answer has nothing to do with your question.
I have both Connect and Jerboa installed, they’re both fine. Connect looks prettier, and the search is definitely better. I end up using Jerboa more out of the two.
When I want to cross-post from mobile I end up switching over to Lemmy’s mobile web interface, which can be saved to your home screen as a progressive web app. Not a Jerboa-native solution, but I’ve tried a lot of the Android apps and I haven’t seen any of them support a proper cross-post.
You were banned from the community and are no longer allowed to post or comment there, there’s a public record of this in the modlog: https://lemmy.world/modlog?page=1&userId=29397
The best practice is for the mod to put a comment in when they ban someone about why they did so, but there’s no such comment in your case. You’d have to look back through your post and comment history to try to guess what you did in that community around 2mo ago when the ban happened.
It’s also a good practice IMO to do temporary bans for first offenses, but the mod in this case appears to have issued a permanent ban, so you’re done interacting in that community unless you can message a mod to request being unbanned.
Some mods tell you when they take action, but many don’t. It would be cool if Lemmy itself notified you, but it doesn’t… you have to search the modlog to see.
