Autocomplete suggestions stopped showing

K9 used to show me suggestions for autocompleting email addresses. Stopped doing so about a month ago. It has access to my contacts. Any ideas? Id reinstall but don’t want to redo all my server settings. Granted, my phone is a bit flakey - Zenfone 9

Reinstalled. Looks like k9 is not finding all my contacts when it pulls up suggestions for the “to” field . I chose “add from contacts” and it is only showing a small subset of my contacts in the contacts app. Does K9 have its own list of contacts or something? Again this stopped working a couple months ago.
