I use KeePassXC (strongbox on phone) + Nextcloud. Everything is wonderful except for nextcloud hiccups. I recently uploaded a resume and realized after it sent that the metadata was incorrect and a local file rename must have been overwritten. Embarrassingly, I had to send an email with the right resume. I sent it from my phone. Right after I checked on the sent email and found that the nextcloud file through ios files uploaded 86 bytes of junk rather than my resume, so I had to send another email.
