Sounds like you may need to sync the app with the website - located under the top right gear icon on the main app page then “settings and sync” and then scroll all of the way to the bottom and hit “synchronize all”.
SSI logs are a total cluster, both the app and online versions. Verification instructor/codes are added as people who were on the dive with you when they weren’t, there is no longer a place to add surface interval times, comments are deleting themselves, “kind of dive” icons are overlapping each other on the app and on and on the problems go.
I had to recently dedicate a weekend to doing them all over and then switching back and forth between the app and website to figure out the secret combination to get everything to save correctly before verifying all of them at once (because for some reason towards the end it would start verifying all of the unverified dives everytime I would verify one dive…)
SSI really should step it up and correct the many issues; I know I’ll never let my logs get behind again lol.
Edit: top right, not top left
