Right now the Squawker fork of Fritter is working fine. You can export from Fritter and import into Squawker (and presumably vice versa if Fritter catches up). It's in the IzzyOnDroid F-Droid repository: https://apt.izzysoft.de/fdroid/index/apk/org.ca.squawker
The latest CI/GitHub Actions builds have a fix for this implemented already! I'll be publishing another beta once I have enough time to QA all the latest changes on the Fritter and Twitter side.
