When the Jerboa app updated to v35, it made it almost unusable for me, since that version and higher is only compatible with Lemmy v18. Since lemmy.world is still on Lemmy v17.4 (because they removed the captcha in the signup process in version 18), I uninstalled Jerboa v35, and downloaded Jerboa v34 from Github. Now Jerboa is working fine for me, without any problems.
