TinyWEB DB and connection issues

[D_M]

Hi everyone and thank you to all the community for the help to develop apps!!

I'm developing an app in which I save events. I currently use the companion to test the app. I use TinyWEB DB and the structure is

---

TAG1 (list) VALUE1 (event1, event2,...)

TAG2 (event1) VALUE2 ("event1 uploading time" ,...)

TAG3 (event2) VALUE3 ("event2 uploading time",...)

TAG...

I retrieve from TinywebDB a lot of tag, for different tasks of my app, so I have introduced a variable "global deleting tag " in "When... got value" block.

My app shows in a listview events younger than a week (604800000 ms), and I have usually no problems, all perfectly work.
But sometimes (I made no changes!) events disappears from my listview because they disappear from the TAG "list" (I check for "list" values online at the address of MIT server http://tinywebdb.appinventor.mit.edu/)

Attached 2 screenshots of blocks I use.
TAG "list" is deleted in orange.
"event uploading time" is at index 1

Is it possible that this is due to connection issues? (problems with "event uploading time" value retrieve, or problems with get mills now value?)
Is it possible that this is due to companion?

Thanks a lot to everyone!!!

Export your .aia file and upload it here.

MIT's Tinywebdb service is not for long term data storage, only for short term testing.

I Know that MIT tinyweb is only for testing.

But I have no problems with saved tags.
I checked and they are all there.

The problem is related to something that interfere with my logic for delete values from my list of tags (my first tag)

Sorry but I can not share the .aia

Prepare a small example project which you can share to elicit the issue, then provide a screenshot of your relevant blocks

Top 5 Scores to CloudDB, Single tag

This is the simplest possible single tag CloudDB sample for a top 5 score list. Sample runs: [first run] [6th Run] Designer: [Designer] Two text boxes are used for entry of player name and score.

Your 'list' tag suffers from simultaneous update collisions.

This is a common problem across all tag/value data storage.
