The "Your services have been updated." message keeps popping up regardless of if I reload the service or not. This has been happening for a few weeks now, and have just been deleting it via dev tools. I decided to report in case others are experiencing the same thing.
See below for screenshot:

If this is not an issue that's happening to anyone else, then I will delete this.
same to me, I had been having this problem across multiple versions of Franz.
A few seconds after Franz starts up, presumbly it is checking for updates, the message shows up on every single service.
franz: 5.1.0
OS: ubuntu 18.04
I've been experiencing this since 4.5-something.
Version 5.2.1-beta.1
OS: Ubuntu 18.04
This has been fixed in the latest version:
Version: 5.3.0 (2019-09-06)
Not resolved; below screenshot is on 5.3.1. Also, now Teams won't work because cookies have been disabled?

Hmm. I also use Teams. And it has been working fine for me. Have you tried copying your recipes and just doing a clean install? That might help. If it doesn't, I will reopen the issue to be reviewed.
@ccioanca What is the best way to perform a clean install on Linux?
Which directories should be purged? Will apt-get remove --purge handle this properly?
@cmccandless I think that sudo apt-get --purge remove will do the trick. I have no idea if it leaves behind configs or empty folders. But I would assume it doesn't. Give that a go.
A clean install seems to have resolved my issue.
