When i refresh to see if there are new emails, k9 loops continuously and never brings in new email messages. I have to reboot my phone to stop it.
Nobody can help you without knowing any details, like phone, android version, K-9 version, your server settings and most importantly - a log.
Thank you - I am a total neophyte and appreciate your direction.
Phone: Samsung S20
Android version: 12
K9: Version 6.000
