This is an Android bug.
Repro steps:
Scenario 1:
- Create an activity (either through syncing from Garmin or manually)
- Tag someone in the post (e,g, “@Bob Smith”)
- Notice that a second or two afterwards the tagged person’s first name disappears (so just “Smith” is shown) and if you are still typing, the cursor often jumps around. It’s unclear at this point if the person is actually tagged or not.
Scenario 2:
- Same as above, but in the comment section of a post instead of post description
Repro rate: 100%
