Using DTTG as data store kills Excel on iOS

When I access my files in DTTG via Excel (using DTTG as document provider) it kills excel 100% reproducible when I leave the file in Excel. I guess this is no issue in DTTG, but in Excel, and I would like to know, if any other user also have this issue and if there is something, what I can do to avoid this.

Reproduction:
Precondition: DTTG is configured as document provider

  • Open Excel on iOS
  • Open a sheet provided by DTTG
  • Change content of the sheet
  • Leave sheet by tapping on the “Back” Symbol (<)

Expected result:

  • Excel shows the content of DTTG folder

Actual result

  • Excel crashes and must be restarted

Remarks

  • The changes will be saved successfully
  • It seems, that the issue does not exist in Word (makes no sense for me, but anyhow)
  • The crash happens only, when the content has been changed.

iOS version 12.3.1
DTTG version 2.7.1
Excel version 2.26

  • It seems, that the issue does not exist in Word (makes no sense for me, but anyhow)

Word isn’t developed by the same team as Excel… or Outlook, etc.

I have confirmed the crash, but it is an Excel crash, not a DEVONthink To Go one. I would contact their support team to report this.
