[stefan-niedermann]

Hello @SebastianV-2021

sorry for experiencing such a hick up.

• Does this appear everytime you open the app?
• Or does it happen whenever you click on a (specific?) card?
• Did it happen before you actually imported your account for the first time?
• Did you already try to clear the storage and reimport your account as described in the FAQ you marked as read?

Sorry for all the questions, but given you apparently did not take a single minute to fill out the issue template we will have to ask to retrieve some more information. Without more information I can't reproduce the issue and therefore not fix it 😉 .

[SebastianV-2021]

It took me more than a minute to enter that Bug Report 🙄

I use the app since a while and didn't do anything specific. It happened once. After that I was able to open the app and use it like expected and like before.
Probably it happened because the theme of my phone changed from night mode to day mode.

Sorry if I tough you might be interested in a Bug.

Sorry if I tough you might be interested in a Bug.

That's why @stefan-niedermann was asking for more information. just look at the issue number: 1685. You know what that means? We had 1684 before.

We write this app in our free time and appreciate every hint about whats wrong and try to fix everything we can. All we want in return is a little bit respect for our free time, so we don't need to ask thousand questions first, before we know whats actually the problem. That's exactly what the issue template is for. Please understand that its getting frustrating to ask the questions again, that are prepared in the issue template.

It took me more than a minute to enter that Bug Report 🙄

Now imagine how long it took @stefan-niedermann to ask all these questions. Or even to find the problem and fix it.

I use the app since a while and didn't do anything specific. It happened once. After that I was able to open the app and use it like expected and like before.
Probably it happened because the theme of my phone changed from night mode to day mode.

Now that's helpful, thanks! We'll have a look and try to reproduce it. We'll reach out to you in case we have more questions.

Please don't consider this message as a front, I just want us to get along with each other, since our target seems to be the same.

This happens to me occasionally. Both with the latest fdroid app version and the dev version you shared with me in another issue ... It seems to happen only if I haven't accessed the app for a few hours. I'll post the error log if/when it happens again.

It happens upon opening the app. I've also disabled all kinds of battery optimisations and given full autorun privileges. My backgdound sync is set to 15 minutes. I've also noticed that with the "dev" flavour I can manually reload by swiping down, while it doesn's seem to work on the regular fdroid version - it just refreshes the cards at 15 minute intervals, but manually swiping down shows an indicator but appears to do nothing.

I've just rechecked - battery optimizations were on for the dev version. I've removed them now and will report back if this was the cause of the problem.
